I’m glad u left everything in the video where the carburetors did not work. That’s real life besides editing it out of the video. Thanks
Thanks for sharing.
Extra credit, James, for taking the effort to preserve the original stickers/labels. It adds value to the engine (per "curb appeal"--that first glance, gut feeling "Would I pay $xx for this genny?").
drill two holes though the frame each side.... pass the ubolt through the frame.
Great job refurbishing it !!!
You remind me of Bruce Pender always neat and clean. !!! That’s good
Rust-oleum makes a clip on handle/spray adapter that is not expensive. Makes it much easier to get a smooth layer of paint. I am a little surprised that even with OEM carb it hunts and surges. Still an air leak?
Good job of restoring a beast.
Just FYI: The trade name is misspelled in the video title. Great job fixing up that generator, by the way!
You could open the main jet a smidgeon with a Micromark modelers drill set.. Not supposed to do it but a good experiment that would work.
Thanks Eric for donating something for us to learn from.
Whoo a new video by the king of generators
We say Mr. Generator!!! He is the man!!!!
@@KensSmallEngineRepair YEAH he is like the clone of mustie
Excellent work James. Really great seeing you bring back a rusty, broken down gen and make it come alive again. You have such a good mindset
James, that was a great video saving an generator that most would have written off, I hate the disposable mindset. I watched in disbelief how you can take a rusty, beat up generator, spend a little TLC on it and bring it back to life and make it look really good with a bit of cleaning and paint. I appreciate anyone who saves a neglected piece equipment on principle and brings it back to becoming useful. You have one of my favorite small engine channels, I fix small engines on the side such as riding mowers, 2 cycle and push mowers, you have motivated me to mess with generators which in the past have always scared me off due to the technical nature of trouble shooting. Thanks for the great content. Have a great Christmas and for us all to have a better New Year.
Glad I could help. It is a common thing that most small engine guys run the other way on the electrical side of things. Have a Merry Christmas!
Making parts like a Boss 💪, Merry Christmas Mr James.
James. you work wonders. made and old one look new again and run as well also. great job.
You outdid yourself on this one. Noticing the additional hole in the main jet passageway was something most would have never noticed. It actually looked like it belonged there. Great catch!
That carb looks very similar to the one on my push mower with a Tecumseh engine. When it needed replacement, I found a clone version with mixture screws instead of fixed jets. It's nice to be able to dial in the mixture yourself instead of relying on luck to get one that's jetted correctly.
I agree. Adjustable jets would make it so easy to fix carburetors when not running well.
I have the same exact engine generator setup on a different style frame it's a porter cable, rated at 3250 watt. I bought it brand new and the only problem I have had with it is that the fuel tank cracked from vibration and I had to replace it. It has always been stored inside and in a heated environment after being run out of gas. I also have bought 2 new Honda generators. A EU6500is and a EU2200i, which have been trouble free. Maintenance is everything! I really enjoy your channel. I also work on small engines and have learned a lot from watching you. God Bless you and have a Merry Christmas!
Got to love when the fuel line will spin freely on the fuel barb but absolutely refuses to come off the barb
The way you added the wheels was brilliant... I have a harbor freight genset with tiny wheels that I've always wanted to put larger wheels on... your method has given me the needed inspiration to do it. Thank you for the great videos!
Thanks
Merry Christmas James. Nice catch on the carb issues, now you have more spares.
Thanks for sharing.
Great way to spend Christmas Eve,
Thanks Jim.
Merry Christmas.
Way to go JAMES! I REALLY enjoy your videos. It’s really nice to see a young guy take the time and make the effort to bring something that most people would just scrap, not only back to life, but then make it something that anyone would be happy to own and use. Keep up the good work👍
Thanks! I enjoy the challenge.
Very cool of your neighbor to bring it back to you and very cool donation for our entertainment
If you look up "trim clip pliers/panel clip pliers" you will find a tool that repurposes for removing fuel lines, or many types of flexible/rubber lines from fittings. In fact it became the major use of those pliers. Plus you can also use it to remove car trim panels just in case. Really like your content.
My dad owned a 68 VW Beetle and I ended up adjusting the valves every six months to keep them from burning up. How many generator owners have actually adjusted their valves. I agree that most generators are not run daily. Your videos are an inspiration for all DIY small engine repairs. Keep them coming.
Great job as usual. Thank you for sharing your video with us Merry Christmas and Happy New Year Ed
Red paint came out nice
I picked one of these generators up at a yard sale this summer. It is a beast, runs like a champ! I added a nice exhaust system off of a Yamaha dirt bike, works well. Nice and quiet! Definitely worth the repair! I put the P3 in rice when it got wet, fixes the moisture issue.
You did great! Happy Holidays!
Same to you
Well done James buddy happy Christmas 🎄 👍
Great video as always! Merry Christmas Mr.Condon.
Happy holidays!
Nice from 33 psi of compression to 70psi always amazes me working on motors how much simple valve adjustment makes
Another awesome video. Great job figuring out the carb mystery. Brilliant paint job also. They definitely don't build them like that anymore 😁🎄🎄🎄🌲🌲🌲
Merry Christmas James and Family. Thank You for all the great videos of this year. Plus keeping me entertained in these trying times.
Happy holidays!
Another nice build James!
Merry Christmas 🎄 🎅
Thanks, you too!
Great video. A guy on a car restoration channel calls a paint job a Craigs List Rebuild. Thanks for sharing.
Excellent detailed video.
Good job!!!... merry Christmas Mr. James!!!
I have that same generator, Had chronic issues with it , gave up on that tecumseh engine and found a briggs and stratton model that fit as a perfect replacement.
Here in Maine, when we fix something like this and make it right, we call it "fluffing it out". James fluffed out that generator.
you are brilliant again in your ratio of info to visual, but shout out to say i appreciate your level of minimum standard you hold. professional my friend.
Great video! Have a blessed holiday! Stay safe.
Nice clean up James 😊
Really enjoy your videos and your trouble shooting methods. You're good!!
Thanks I have the same generator and that fuel line was the worst so we relocated it and got new carberater so now. It runs great
Great videos. I have learned a lot over past couple of weeks. One tip when using multimeter with a rotary switch > turn off the meter when switching mode from AC voltage to Hz. There is a chance of creating a voltage arc between contacts within the rotary switch, when switching modes and having high voltage AC is on the probes. I know this from experience and destroying a good meter.
That was a tricky one with all those carb. trials but good thing that you are familiar with them so that you could pin point the engine running problem. And now it is a great looking unit that someone could make good use of!
Great job James. I had a similar Tecumseh that would not run right and finallly found that the gasket from the carb to the engine block was missing on the far end of the intake manifold. Someone took it out and left it out and it was sucking air. When I put a gasket in it, it ran like a top. Tanks for the video's.
I was wondering the same thing. The connection looked undisturbed, but should probably take a look to be sure.
Who gets free generators and someone to deliver them free from eight hours away send some of that Luck my way James have a great holiday!!!
Great video James 👍
Great job Doc.
Thanks for sharing. That was a bit of a tough one.
Merry Christmas James 🎄🎁
Hope Santa brings you a sleigh 🛷 Filled with broken generators.
Hahaha 😂😂😂😂
Thank you I feel I can start a generator repair business now .
Great work James! That was kind of an oddball there, both in the gen head and the engine. Those last generation Tecumseh OHV engines were great when setup for snowblower duty where they can run rich but they seem kind of fiddly when setup for general use. Between the tight EPA regulations and the same bare bones carb design that they’ve used for decades it seems kind of hard to get them dialed in just right. Looks and runs super!
I could not have scripted a better progression or outcome for a donor unit! As always, very fun and educational to watch. Such a bummer that 2 clones and a modified OEM carb didn't run right for sure. Great mods by moving and tweaking hardware from that Troy-Bilt frame. Love the new bar bender, wheel mounts and red paint too! No tire dressing!? 😉 Thanks for delivering an early Christmas gift to your regulars and have a Merry Christmas, James. Hope the winter brings you power outages so you can move rehabbed units to make room for more!
They are forecasting 40 Mph sustained winds tonight with gusts up to 70. Might be moving some equipment Christmas Day. Have a good Christmas Eric and thanks for making this one possible.
@@jcondon1 Wow! Yeah it sounds like you will be open for business on Christmas day! Good luck and you're welcome. Was my pleasure and special thanks to Joey for literally being the middle man too.
Great job, that was enjoyable.
Thank you very much!
Very nice! I like your new bending toy!
For preference I favoured the blue paint and a wipe over the plastic parts (tank and air box).
Your persisence is legendary!
Thanks to Eric and Joe also!
This video proves that having the ***correct*** valve clearance can make a huge improvement in engine performance and horsepower.
When I suspect an intake leak, I spray ether around flanges, and other possible sources. It really was a great help, when I couldn't find a leak.....
Just an FYI the lower HP Tecumseh carbs had pressed-in brass emulsion tubes. Happy Holidays James! Stay safe!
Good job!
Man that one was a naughty little fellow. Between mal-adjusted valves and goofy carburetor problems this one was difficult to get fixed and running well. But kept with it and got it fixed to work another day. Excellent fix and repair to make a good little generator for someone. Good job Generator Man.
Thanks. This one was a lot or work, but it was free so worth the extra effort.
Great save James . ENJOYED !!
Thanks
Nice Eastwood bending tool love getting new tools
I wish u would’ve given us the heads up when u were using the grinder to cut the handle off. That was all in our eyes!!!!! Lol
you made it a lot further with that Tecumseh than I ever did. I hate working on those things. I usually put in some repair time then pitch them.
Hi James. I was the Product Manager at DeVilbiss for several years (probably during the time when your generator was built.) I am impressed with your knowledge of generators and small engines, and with your determination to get things right. As to the genhead, you are correct; it is of very high quality. In addition, the laminations in the stator are skewed, which helps to ensure an extremely low THD. Although I can't say for sure, I suspect that it is actually a 4kw head, and if I am right, you could attach a 7.5 or 8 hp engine and get another 500 to 1000 watts. An 8hp Honda GX or a 7.5hp Briggs Vanguard would be a good choice. Thanks for your video.
Thanks! I try to get them right as possible. The DeVilbiss generator heads are very good. Not sure I have ever seen one that does not make power. Many manufactures make a generator head that can handle a range of power and just throw different HP engines on them.
@@jcondon1 Brushless genheads sometimes have to be "flashed" if they have not been run in a long time. You probably know that and maybe have a video about it. It's an interesting process.
Merry Christmas.
Yet again another kick ass video. I learn a little more on each one. Great work as always.🤘
Thanks!!
Nice work ! MERRY CHRISTMAS
I haven't seen many generators with Tecumsehs in them. This one should be interesting.
Nice video as always. Thanks again
I fixed a similar one. These are great in the middle of the night as the neighbors can hear it for miles. After awhile you can just hear the motor and tell if it is surging or is at the right RPM. Often you find the carb full of old fuel. Most times inside the carb the fuel has turned to sludge and is not easily cleaned.
Great vid! I need to learn to weld. It would come in handy. I like when you customize stuff and make it work.
Thanks 👍
I really like those engines.
Fun video, just need to admiral the tires;-) LOL Thanks!
Greetings from Idaho, I enjoy your videos, Merry Christmas 🎄🎁 and Happy New Year 🎆🎊. All the best to you and yours and stay healthy!
Thanks!
Wow got replacement carb in the mail installed and it's doing the same thing at the beginning the very first carb did this is the 3rd carb and still issues very intriguing 🤔 @39:20 @James Condon
Very good learning video. Hey the Harbor Freight down here on the Ms Gulf Coast had Kill a Watt for $25. In retrospect it's good that the other frame did not fit, because I don't believe the engine had a oil sensor which could spell disaster should the engine use more oil than thought. Either way it's always wise to check the oil level slot in these situations..... enjoyed the video..Merry Christmas to you and your family..
"It handled a load 45:39 also without issue." That's what HE said! Yeah, I'm going to hell! LoL Merry Christmas!
I have had the same experience with clone carburetors.
Finally found the answer. It has to have two diodes and a rectifier. Sometimes it is hard to find stuff on the web.
Never seen the 120v plugs on the cover of the power head before very interesting 🤔 🤯
I lot of older ones have that.
@@jcondon1 very neet I live in a dry desert state don't see generators much here other then on store shelves
You're like Mustie1 but focusing primarily on generators. Nice informative videos.
That's the kind of generator that defines "bare bones".... No big tank, not a bunch of outlets. Likely marketed for a job site, to run tools in short bursts. That's a decent engine for its time.
I enjoy your videos. You have a calm and concise voice. You need to get yourself a small MIG welder to repair small things. Build brackets etc.
I'm a retired machine designer and spend my time on garden tractors, small engines, art welding and a little fabrication. Have a great New Year.
Thanks. Actually just picked up a used 240v one. Need to do some wiring, get a tank of gas and a cart. It will make an appearance at some point.
Another way to remove grips like the ones on the handles is to use a screwdriver to pry it up enough to get a blow gun from an air compressor under it, then hit the air. That inflates the grip enough it usually comes right off with no struggle or force. Those grips might have been a harder plastic than typical motorcycle grips, so it might not have worked as well. Looks like you got the Eastwood 4 inch bender. They make good stuff. There are metal brakes that are made to work in the same way on a bench vise, but I'm not sure yours is sturdy enough for those. Keep up the great work!
Looks good fun project
Another great video James. You had me shouting buy a welder and now I reckon Santa will bring you one lol Merry Christmas to you and your family from us guys here in the UK.
Thanks 👍
I know that feeling when you buy a clone carb and the old one works better than the new one.
About time you got some tools keep struggling a lift up cart bench to save you on the floor working
Wish I seen this video a few weeks back for the axle brackets.
As always,Nice video
Appreciate that
You can also use a pipe or tubing cutter if you have one handy.
Merry Christmas! Try putting your Kil-a-Watt meter into a plastic bag of rice for a day or two; it really works to dry out electronics effectively. Good Luck!
It is working again. Bought a backup just in case.
Its kinda mind blowing that you don't have a welder. Being as talented as you are. I just bought my first welder a week or so ago and oh my gosh is it awesome to have!! You'll definitely benefit from having one.
I now have everything, but the welder. Looking forward to getting one.
@@jcondon1 oh it will totally change your workflow. Its so awesome to have! I keep thinking I have everything lol. Until I need something like a tap and dye set and boom off to the store I go again lol!
Tecumseh ALWAYS a pain to get running right
Excellent Tech 2/19/2022
Saved it from going to landfill, nice job
Thanks
When putting an engine back in service, put some berryman's #12 carb and fuel system cleaner. Works well to ckean out crud and varnish..
