- I tear into this old chainsaw to fix it, and it has a few surprises in store for me. It didn't occur to me when I was working on it, but this saw is an antique at 43 years old. This turned out to be an enjoyable but tricky repair!

Yep, this was a tricky one, which for me makes it more enjoyable in the end. Though it did take me awhile, I'd take this over just rebuilding the carb any day. Ignition tester: amzn.to/48SdqEG. Electronic ignition module: amzn.to/3v3pNQo. Have an awesome weekend everybody!
Curious if original carb ran the saw after ignition repair?
I only watch for the seals
I've had many years ago (~2000) a similar problem with a 79 Ford Taunus (German made) carburetor that would not start the car in cold even if you asked it nicely... After a fewf clean-ups and some repair kits I ended up putting a flange and a carburetor for a different car with similar size engine. Went to a dealer, changed some jets and they tuned it and worked like I a charm. It still bugs me to this day what I didn't know that could help me fix it.... After a few years I drove the car for the last time. I've noticed that the car run perfectly and my father noticed this as well... It was a bitter sweet moment. That was the car I put my most work into and thought me a few things about rust and what one can fix and when one should let go.

I have an Old 41 Farm Boss I'd like to have rebuilt that's about 45 or 50 years old. Is something you can successfully work on?
Jon, if you were not a teacher in your previous worklife, you really missed your calling. I learn more from your informative and well presented podcasts than I did in most of my high school and college classes. Your tenacity is amazing, your videos are technically superb and your presentations are well paced and mixed with a nice blend of humor. I hope you keep up the great work for many years to come and I wish more presenters on CZcams could take lessons from you. 👍👍👍
The kind of teacher we all wish we'd had
Agreed.
wonderfull explanations, I have the same saw, and have the same problem, thought it was chock issue, and now I believe I need to check the spark, great thanks.
Truth!
The learning model....rote memorization, understanding, application, and correlation....
Memorization is useless for this, but understanding the functionality, applying the concepts, and correlating the lessons learned to future problems is great.
And to integrate those while working through "failures" is where he shines.
I bought my Stihl 028 Wood Boss in 1987 to clear off an area for our new house. It has always been a great saw. After watching your video, I discovered the manual says it has an electronic ignition, so that should be good. Over the years though, I have rebuilt the carburetor with new kits and never had real good luck with them. In the end, I replaced the whole carburetor with a cheap China one from Amazon and it has worked like new ever since! It is the only chainsaw I have ever owned and definitely don't consider it an antique!
I bought mine in 1986 and use it regularly. I burn 4-5 cords per year. Along with an 036 they run great and still going strong.
That grinder on the lathe... It's both hilarious and genius.
As soon as I seen the grain grinder on the wood lathe I started to laugh.
@@DB-yj3qc Same. I sent the screenshot to some of my friends. Still laughing.
haha i had to share that too with my friends @@saxus
You said grinder, I thought you meant abrasive. Maybe a flap disk. THAT did NOT even register as a possibility!
48:27 caution lazy man at work beware of spilt beer"
Sounds like it's crank seals John. Put a cap on the exhaust and pump it up. If it leaks, pull the engine apart and reseal it. A couple of hours will make a dandy saw.
John Do a leak down test on that motor to make sure you do not have crank case leak. The 028 is known for bad crank seals/ impulse line/ intake manifold boot. Also the coil you bought is a electronic ignition coil. Just hook the kill switch to it and it will work. Do away with electronic ignition module if you want to put that new coil in that saw.
Well that is some incrowd knowledge, really nice
That was I thinking Leak test it.
Lots of hard issue come from Leak test
Thank you for these tips! I'm never too old to learn new things.
Man always looking forward to this wholesome dude fixing sh... !
It? For $1000 Bob.
This is what I love about old mechanical tools, they're fixable! I like the electric stuff but man when they fail, they're not easily repairable and I guarantee they won't be lasting 40 years like this saw!
I haven't found too many modern tools that can't be repaired; they just need different skills and sometimes a creative method of sourcing parts.
@@watcherofwatchers that’s a good point and great perspective. I’ve soldered connectors back to Bluetooth speakers and resisters back to boards but the new tools seem so cheaply made, sometimes it’s better to replace than to fix. Love the content on this channel, though. Fixing things and bringing life back to stuff is cool regardless of what it is.
I purchased my 036 new in 1994. We heated with wood exclusively for 10 years and every bit of it was cut with it. When we purchased 20 acres of wooded land it’s bee used constantly to keep the land cleared of damaged trees. It’s never had ethanol blended gas in it and it’s ran on Amsoil Sabre oil exclusively. If I went out to the barn right now it’d start on the third or fourth pull. I’ve put numerous bars, chains, gas filters and clutch sprockets on it but the engine remains untouched.
Stihl built a great saw back then.
I bought this exact saw around1980. I have cut many cords of wood with it since then and it is still going strong. One of my favorite saws and I have several. This was considered to be a PRO saw by old timey repair guys as it was manufactured before STIHL started making three levels of quality. I refuse to look at it as an antique cause then I must be old {77}.
I have an old 028 myself. Watching I was having flashbacks from about 7 years ago. I pulled points out and added module. starts everytime and runs great. One of my favorite mid range saws
Right now there's hundreds of guys in there garage fixing this exact problem. Great vid ..Great edit..
Hands of a surgeon…brains to match , a man that can do everything and I mean everything deserves respect , well done as always !
Every Friday when i sit down to chill, i load up CZcams and immediately look for a FarmCraft101 or DieselCreek video. Love you guys! Keep up the good work, fantastic entertainment.
Congratulations you have more patience than I do
43 years makes something antique? Man, I feel old this morning.
Agreed, that's my main saw and I got it as a wedding gift brand new from my father-in-law.
Love your videos!
My Daddy taught me something very valuable for memorization in these situations. "I'm not a fig plucker, I'm a fig pluckers son, but I'll pluck figs til the fig plucker comes!" When you encounter a troublesome machine like this, repeat this phrase three times. Things will become crystal clear!
I’ve a similar one. “I’m not a pheasant plucker, I’m a pheasant plucker’s son, I’m only plucking pheasants til the pheasant plucker comes”
The high speed jet should be adjusted at wide open on the trigger while under load in a cut. This is why saw shops used to have a big hardwood log out back before government took away the adjustment screws. There are screwdrivers that lock onto the jet to make this easier. Same thing, find where it starts stumbling in both directions and put it in the middle. You'll be amazed how much more power you can dial in.
Turning the high screw on full throttle with no load until rpm is the highest then backing it off until it '4 stroke's also works
Great video John, very enjoyable. Small engines can be very temperamental hey! 🇦🇺🍺🍺
The official Stihl way is to adjust no-load RPM at full throttle (with an electronic RPM meter), but I also usually use your method.
100% wrong. There is a spec in every Stihl Tech Manual for a top no load speed setting. The high is adjusted 500rpm under that spec for a saw that is broken in and 1000 for a brand new saw. It should be adjusted using a digital tachometer.
I have an 028wb just like thar one from virginia beach. Went thru that same repair about 3 years ago. Ive had this saw since it was brand new around 81 or 82. The only saw ive eber owned. Im now 71. Great saw
That was an invaluable invite into chainsaw repair , I have experienced all of thease symptoms in the past, I will now use your method to diagnose and repair , thank you for sharing your knowledge and time
School is in session...loved the trip down the rabbit hole with you! thanks for taking us along.
First thing I do with a non running saw is check compression with a tester. If someone puts the wrong gas or mixture in (it happens a lot) or another issue leads people to turning jets….. making a lean mixture. Both will burn up the piston and cylinder very quickly. With a saw that runs but not great, pull off the muffler and look into the cylinder. Then rotate the engine slowly and look at the piston. Exhaust side is the one that gets burned up from excessive heat. Just a small amount of scoring will drop compressing causing it to run or start poorly.
Loving the fact you just never quit. Unfortunately it’s not very common quality
Jon, good job on your stick to it mentality. When I was having a problem with my Stihl bogging down I talked to my Factory Stihl Repairman and he told me to only run 92 octane fuel with the 2 stroke oil in it. If you can get it without Ethanol it is even better. I changed the 89 octane fuel to the 92 and wow, that really fixed my bogging down. I am sure you already know it but this was news to me and I thought I would share it with you. Great video. Oh and the flower grinder was priceless. You think a lot like me. hahaha
Yer tenacity is an example for us all, my good man, thanks for sharing!
I have a Stihl 08 that my dad bought in the 60s. Folks around here gave him a lot of flack for buying a "foreign" chainsaw! I reckon he had the last laugh as it's still in good condition.after almost 60 years. Last time I tried to use it, I could not get it started. I took it to the local Stihl dealer and they fixed it for free and thanked my for allowing them to work on it! I was astounded, to say the least.
Thank you from Sydney Australia. Fantastic instruction video. I've got a small saw that's 'more than likely' the same issues. 🇦🇺🌏
I don´t have to maintain machines due to working in an office, but watching your vids is always the start of my weekend...interesting, sometimes sarcastic and always self-critic...thank you for sharing your work with us!!
Most guys would have chucked it in the garbage, your persistence has paid off . good repair video.🤠
I ordered both PC-7 & PC-11 as I needed some good epoxy and this stuff seems really good.
I also have them and they are great, BUT they are slow to cure (hours). If you need something fixed quick, get JB Weld KwikWeld or similar.
My old 038 magnum is by far my favourite saw. Takes a minute to warm up but once it does it'll run all day
I have 1 just like it I'm so blessed It was my father's now mine Never been in the shop yet When I need to if anyone can ever fix it I love my saw. Thank you thank you for the video.
I've had an 026 (slightly smaller, but still pretty beefy) since the early 90's. Spent many summers in my youth working barbwire crews in the foothills, cutting back brush and saplings from fenclines with that saw. I inherited it from the crew I worked with as a bonus at the end of a summer after working with the same crew for 4 or 5 summers. One of my favorite things about the Stihl, was the multi-tool it came with. That screwdriver/socket combo tool was life saver, and it was amazing just how much effort the engineers put into making sure the vast majority of repairs could be done with just that one tool. Anything that couldn't be solved with that tool in the field, meant it was beer o'clock. Unfortunately, the saw was so well made, and you could fix/tweak so much with the tool, that would only happen maybe once a summer.
Still have it. Hardly gets used anymore. So a light tune up every couple of years, and she's good to go. Pro-tip: When the pull cord breaks (it will eventually) replace it with good quality paracord, and you'll never have to replace it again or worry about it snapping when you really need it to not.
man, i love these videos, i never would have guessed there were points under that flywheel, always learning something new
Great video, thanks grand master chief for the depth of your knowledge and unlimited set of skills.
I had a Stihl 051 with a 36 inch bar from the same era as your 028. Thing was a beast.
I love the little details of these small combustion engines. Thank goodness for brilliant engineers and inventors that came before us!
I wonder if a neurosurgeon has as much patience and determination as you! Good job and thank you for taking the time to film this for us! Someone gifted me one the these things so I feel prepared to attempt to turn it on now that I’ve watched this. 😂
Great diagnosis video for the old Stihl chainsaw!
I would not have guessed that a chainsaw made in 1981 would still have had non solid-state (points & condenser) ignition, & since electronic ignition is usually very reliable (& durable), I didn't suspect bad ignition as a likely cause of the engine's non acceleration issue (I imagined the issue was almost certainly carburetor related).
When you decided to replace the condenser with an electronic ignition module, I thought that theoretically (& ideally), that should be a big improvement (over points & condenser ignition), but practically, I thought the fit & quality of the aftermarket electronic ignition module might be questionable, & so I thought it might have been better to obtain Stihl OEM replacement points & condenser (to insure proper fit & quality).
After all your diagnosis, I'm sure you would have wanted to determine the cause of the engine's non acceleration issue, without additional uncertainies of replacement part quality (such as the new aftermarket coil, which was bad "right out of the box).
Regardless of the aftermarket electronic ignition module issues, I think you did a thorough & meticulous job fitting all the ignition module parts & wiring, & did great work overall!
The old chainsaw sound great!
I had a 024 wood boss back in the day. It was an absolute tank! Lost it in a garage fire. Always wanted to do a resto on a beat 024
I still own an 028 that my father bought when I was 15 y/o. I'm now 61! Still a damn good saw, which I've cut a lot of winter firewood with. Never have torn it down. I've just serviced it over the years, and replaced the bar once
John seeing that saw brought up memories of me teenager years, cutting and loading firewood.
I rebuilt my Dads old 041 from 1978. You would be amazed at the amount of parts Stihl still has kicking around for factory parts including carb rebuild kits, bearings, etc. I did have to go aftermarket for some stuff, but I expected as much. The saw runs pretty well now.
Another great one! I learn so much more and enjoy watching your complete and very detailed video repairs! 💯
Your films are always very interesting whenever you're fixing stuff. Please keep making this kind of movies.
My first saw was from that vintage. I got it well used in the early 90's while attending college and still have it. It is a Stihl 009L and thank dog the chain oiler still works.
Love the grinder on the lathe. I have an old 024 I need to work on. Thanks for the video
I got that exact same saw from my dad too! Mine runs like a top, just had to give the carb a good run through. It’s a workhorse and does an awesome job. Thanks for showing me the air filter splits apart, I had no idea.
Oh that special, fuzzy feeling when you diagnose and fix something that's broken 👍
How addictive!!
Always like Stihl equipment, high and consistent quality 👍🏼
a great in-depth tutorial. thanks for magnifying the carb rebuild . sure makes it easier to understand .
I came acrost this channel about 1 year back and I have enjoyed it immensely since. I have even gone back and watched some of the past posts. You have never failed to entertained with your content. Please keep up the great work. I must tell you some times you just plane crack me you with some of the things you say ! 👍 👍 👍🤣
I inherited this exact model of chainsaw from my father which he bought in the late 70's or early 80s. It runs great. Always starts on the third pull even after no use for over a year. But once it gets warm after about 5 minutes of use, it sounds just like your saw. I think I'll try this ignition module and see if that does the trick. Thanks for the video, its such a great resource when I go to do work on my saw.
Interesting points ignition. I grew up mid 70's points ignition mini bikes. YZ 80 yamaha always playing with timing. 14 and 15 years old fun with mates similar bikes. Memories 61years old now.
Wow, thanks for reviving the old 028 Wood Boss. I purchased mine in 1984 and ran it hard for 30 plus years before giving it to my younger brother. It still lives on at the farm cutting fire wood. Brother tells me it runs better than his 2 newer 025's. Besides chanes, bars, drive sprockets, spark plugs and some other small maintenance items, still starts on the 3rd pull after sitting for a week and 1 pull after running and shut off for a break. Dont make them like they used to.
Good video, maybe some gaskets and crankshaft seals need to be changed, especially due to the years of the saw. Thanks John
I absolutely LOVE your grain mill drive! Creative solution. As for the saw, your methodical approach to fixing it may have taken a little longer, but you know everything else is good. Ditching the mechanical points is something I may not ever have thought of. Really appreciate what you do and share with is all. THANK YOU!
I have replaced the mechanical ignition on both of my Suzuki cars. And I instantly gotten stronger spark and like 5HP extra instantly. (which is a lot in a car with only 50 factory HP to begin with)
This is educational clean entertainment that should have at least 5 million subscribers.
I have that exact same saw. STIHL 028 WB. Was my Dad's. Good video.
The weekend always starts nice, when there is a Fridays video from John.
Been watching for a couple of years now. My favorite channel. I have learned so much. Thank you for sharing!
I put a conversion kit on an early seventies Jonsred saw of the same size, it did the trick. My son is still running it today. Good stuff.
This was one of your best videos. You covered all of the “mysteries” of small engine repair that we all can use to better diagnose and fix a variety of issues. I feel much more confident tackling problems that arise with these engines now. Makes me want to revisit an issue I’ve been having with my tiller! Many thanks to you Jon!!
Our .o32 takes two pulls with choke on, fires, chole off & it's ready to crank and cut wood. It was this way when new and today about 15 years old. Stihl is hard to beat. I am amazed at your patience and the few bleeps necessary to complete a project. Good info & video.
LOL.... I walked out just before you found the points the last time I watched this, watching it again and I was thinking I bet theirs points in that thing ! and sure enough... the way it was running just pointed to me the points/condenser the condenser in particular in this case
...my hats off to you as I bought one of those little electronic ignition module a long time ago and I fought it for a week trying to get the thing to work and finally gave up and put the points back in it ! (on an old B&S 3.5 hp).... I never seen any of those things work !
I've had friends tell me nah they are junk, they don't work ! yet You got one to work WOW !
I've had several saws with points in fact I think I still have 2 !
it would have been really interesting to see if just replacing the condenser cured the problem.... but I guess we'll never know now ! HA !
Thanks Jon for the great videos !
Enjoyed the video. I have an old Farm Boss. You are persistent.
Fuel lines are replacement items. Over time the rubber disintegrates causing cracks and leaks. When you needed a clamp on the fuel line it indicates that it was on the way out if not gone. At that time it makes sense to change the pickup line as well. Change the in tank filter as well.
Great video. Enjoyed your patience and determination. Ive had an old 028 Wood Boss sitting on the shelf for a fsw years.
This inspires me to get it out and see whats going on with it. You earned a new subscriber.
Two strokes with multiple issues can be a real challenge to sort out. It sounded great in the end. Always worth the effort to save a Stihl saw.
good to see u here lol
I am working on 2 Stihl 028 AV SUPER chainsaws right now. Both belong to a subscriber. One he has owned since new and has sentimental value to him. It ran great until he let a friend borrow it. He straight gased it and burned it up. Well build saws, definitely worth saving.
Yeah more content!! wooot
What an interesting trip. I love learning process, and outro was very cool. Also humor is spot on. 🙂
Excellent troubleshooting and repair 👌
It's easy to have a love hate relationship with chain saws. Its cool you got that one working.
Weak spark always shows up when the throttle is opened because the compression is much higher than at idle. It is much harder for the spark to jump at higher compression. Adjust high speed jet under load. Will get rid of bog down while cutting. Nice video John. Thanks
This was great! Thank you for leading us through your process and improvements you'd make. Really glad you didn't give up on it! This will definitely help me when I'm troubleshooting old equipment
Hi John really love your vids. Had same issue with my Stihl blower . Bought a chinesium carb no problems since 😊
Great video.
A few years ago I dismantled an 026 that belonged to my grandfather.
It must also be from the 80s, it hadn't been running for 20 years and it had ignition problems.
I think I have the same problem.
Great video thanks again for your video 📹 great help for me 😊
Another great video, just one thing I wanted to let you know. The gas can you used to fill up your saws actually had an auto stop with a check ball so you actually can’t over fill it as long as the nozzle is in the tank
lesson learned, diagnose first- compression test and spark jump, then look at fueling. I just ordered the same spark tester straight after watching your post, thank you so much for forging the path for us like minded people.
My 028 starts and runs whenever I need it. Its amazing. I've had it 15 years or more and maybe changed the plug. Chickanic recently did a video on how to flex the diaphram to get it working - once its running.
Fascinating video! I keep learning things in these that I hope will come in handy one day.
My ‘87 high school graduation gift from dad was a used 056 Stihl, I’ve been running chainsaws ever since. Have to admit, I learned a lot from this video that I probably should have known thirty years ago! Thanks Jon
Have one since new! 1990. Only thing I’ve done is new carb from the Hipa Store and new plug probably 3 years ago. Runs like it did new. Cold starts on third pull, first pull when warmed up. A little heavy for a 47cc saw with 16” bar, but all metal! 👍🏻 Thanks for the video!
Farmer ingenuity on that grain mill ....awesome 😊
Hi from guyra Australia enjoy your commentary.
Thank you for sharing this video, great information.
Fun fact: the factory that processes those carbs is based in Tralee, County Kerry Ireland.
I own one of these, my first chainsaw bought it when I was about 14 still got it am now 52.I remember I got it at discounted price because it was discontinued then, lovely saw.
Great work, our MS230 has a similar issue this definetly helps, thanks. You know you got the good stuff when it says "Made in West-Germany" on it.
Another great video , got to get me an ignition tester like that. Would save alot of headaches. Thanks
Saw is two years older than me and still kicks ass! Great video!
I have had very good service from the 20V Dewalt electric chainsaw. It routinely bites off and chews a lot more than I thought it could. Even though I would say that it is really just a limbing or pruning saw, I have made some very big cuts with it. And no small engine temperament to deal with. Just charge a battery and pull the trigger. Though, it is entertaining to watch you trying to get that thing to run right.
At 33.29 he breaks out the Giant crows feet set but never tells why---Trade secret eh!!!!!!!!!!! Great video--Old Cat mechanic here--42 years-still love working on machinery--old vintage saws too!!!!!!!!!!
Points was a surprise! I have a 43 year old 056 magnum I bought brand new and it has electronic Ignition, not the original mind you. It’s my go to medium size saw. I guarantee the modern computer controlled saws of today will not be salvageable 43 years from now.
The spark strength required to jump the gap increases when the plug is in the cylinder and under compression. It takes more voltage to jump the gap due to the higher air density. But, fuel will conduct electricity so that helps get the spark across the gap. A low compression rich mixture takes much less voltage that a high compression lean mixture. That "S" on the spark test tool is the minimum spark length required in free air to get a consistent spark in a cylinder.
I’ve got one just like it that my dad had and used a lot. It sat in my shop since he passed away in January 2012. I purchased 90 acres in Lincolnton Ga. in 2021. I decided to try it out and after putting new gas in it, it fired up on the 9th pull. I put a knew plug in it and it starts on the second pull every time. I cut several loads of firewood with it and I love it!
Ive inherited this exact saw from my grandpa and it has the same issue. I can't wait to try this fix and cant thank you enough for the valuable information and trouble shooting.
Found your channel through the algorithm, I guess. I just love it. Went back and watched your videos, starting with the pond series until now. Wow! ❤
Yep!! He's the real deal!
Same way i found it. It recommended a video he did showing how to sharpen your saw and I've been watching since then
welcome!
Nice one i wish i could start that one over again, but i still remember it all so that’s no fun enjoy
great job on the saw. I loved it.
