This video should be required viewing for all High School students. Everyone should know these principles. They were presented in a clear, concise and easy to understand form. Thank you.
i could never smile as much as this guy while working on broken equipment lol...
This is of course the correct way to do it. Dang it if EVERY time I have a machine go down in the field, it is some obscure, deep hidden glitch. "The most common..." does not seem to apply in the real world.
Who's watching this 2020? Thank you, I'm fixing my trimmer, right now
I am doing a lesson on two cycle engines for school and I thought that the information provided was very beneficial for any homeowner that uses any two cycle engine.
I love how he used Carb Cleaner as Starter Fluid. Learn something everyday.
+1487G Yeah the active ingredient in Carb Cleaner is Heptane. Its pretty darn close to the active ingredient in modern starting fluid and it will get you out of a pinch. PB's rust buster also works. Never use WD-40 though.
Hey Mark,
Dont forget the kill switch wire that goes to the coil,Ive sometimes had those ground out making it seem like a bad coil,And sometimes the kill switch itself will be bad.
Knowledge is Power.
excellent. after playing around with engines for 50 years, and reading books, your video just made it all make sense, once and for all. thanks
I have worked with 2-cycle engines for many years...But this video is most informative and helpful !!
This made me more knowledgeable about, how to fix my machine. I am thank fore for this timely information.
Mark, you do a BRILLIANT job with these videos! You obviously know your stuff and present the information exceptionally well! I've had a handful of gas trimmer problems and I know I can count on your videos and your friendly / cheerful disposition to solve my problems. eReplacementParts did a great job having you do these videos!
Nice job! Good pace, good coverage, and good shots of the equipment.
Thank you so much for your explicit explanation. Excellent presentation. Thanks for unselfishly sharing your knowledge.
Great videos mark! I'm trying to tackle my first small engine issue (weed eater) and your videos are by far the easiest to understand and the most helpful.
Thank you Mark, perfect balance between high level diagnosis and detailed direction. Add a sprinkling of common sense eg electric problem - replace the spark first
Very useful and very informative. You manage to take a lot of the mystery out of these tasks and your explanations are simple and clear to understand, they are a great help, especially to the keen amateur. Thank you.
Thanks for the clear, professional advice.
This was just what I needed. I fixed my trimmer and leaf blower. Thanks for the valuable information.
Mark I work for The Home Depot as a tool tech I get a lot of parts from you guys, I find your videos very helpful. Thanks Slot Tim
A well thought out and well organized tutorial.
Thank you.
thank you sir
you really really educated me on something I had no idea of.. but everyone else did.!
Thank you, this video was VERY clear and simple to follow. I've worked on my cars and on my bikes (very complicated!) and in my many years of doing lawn maintenance I've been hesitant to bother working on my equipment. Tbh, it was a huge job on my V4 Magna that convinced me a small 2 stroke was simple by comparison. :)
Thank you! We appreciate your business and words of praise.
-Mark
Superb videos. You're very clear and well paced in your delivery and you smile a lot. :)
Very logical step by step explanation to trouble shoot the problem. Needs the right tools to get the right result!
BRILLIANTLY MADE. CLEARLY EXPLAINED: THANKS FOR THE HELP :) I'LL BE BACK TO POST A QUESTION SHOULD I RUN INTO FURTHER DIFFICULTY AFTER TRYING THESE METHODS
Very good video, Thank-you. Looks like I am heading down to Canadian Tire to buy some starter fluid. I like how you simplified your analytical approach in diagnosing the problem. Priceless! Cheers.
very helpful. will start through the process and see how it goes. thanks
This video is brilliant and very helpful. Very nice and professional presented
That was super helpful. Thanks! I'm glad this video exists! I wish I looked at it awhile ago!
Thanks for the helpful, methodical approach. I'll begin testing today.
Super video. Very informative & clear cut instructions. Thank you for separating the systems. Including the links was helpful.
Thank you so much for your advice.
Hi Mark is pleasure to watching your video. Very useful and very nice presented. You got the skill to pass the knowledge to people! Gratulation!!
Great video.Concise and put in laymens terms.Thanks
Mark, loved your thorough video on checking for problems for 2 cycle engines. I am going to use what you taught me to check for problems on my Poulan leaf blower. Thank you very much.
This is the best explained video on youtube great job.
great video, really helpful rather than guessing what the problem is.
Very good, clear speaking and the best school ever in youtube. That's simple like that!
It sounds like there is still some debris in the carb. If you can get your hands on an ultrasonic cleaner they do wonders to clean stubborn carbs. You can also try using fishing line to clean the small passages in the carb. Never use anything metal though to clean. The metal will damage the fine passages and the carb will not work properly afterward.
I hope this helps,
-Mark
Mark dose a very good job getting through the process of 2 cycle engines i learned quite Thank you Douglas
Nice video!! Straight forward and clear instructions!!! Thanks!!
Good info, I have repaired many 2 cycles but the compression info was new to me. Thanks
Mark seems like a great person! Thanks.
Helpful. Diognosing a 2 stroke dirtbike now with the help of this vid. I am a first time owner an not super mech inclined.
I feel a lot better knowing about how to properly diagnose a prob
Excellent stuff. Thanks for taking the time. Placing my order for a carb now. Just wait to see how I manage to botch it... but the vid is still great! :)
Nice clear diagnostic video. Now to tear into my trimmer. Lots of little pieces‼️
Thank you for the class. Very helpful
Thank you Mark , much appreciated .
thank you for the video , it is helping me some knowledge about 2 stroke engine .
Thanks for the videos they are very helpful.
Very well done. I've added you to my library.
Well done a lot of the help videos I see on CZcams are filled with umm and it might be... but this has definitive answers thank you for your quality video!!
Great videos. Very well written and informative.
Very good information and very helpful. Thanks for taking the time to do these videos.
I just eat this stuff up! really helps me...as do the comments below...because I don't know (or once didn't know) anything about two-cycle! ME! A kid born in Dayton, Ohio, home of the Wright Brothers and their 1903 original aeroplane (which was, ahem, two-cycle!).
Loved the video straight forward and in depth and with a variety of equipment. You should do a video on how to increase the performance of a two stroke engine
Thanks this video was very helpful!!
Helpful video! Thanks for good job!
Great video. Very helpful in diagnosing small engines.
Cheers Mark, great vid.
That was the best video ever, sir! Great teaching and explanations. I was about ready to just go buy a new trimmer. THANK YOU!!!!
Well done nice video a very pleasant demeanor .
Informative steps in diagnosing a problem
Great job explaining all procedures (Y)
Most auto parts stores offer ignition testers. I purchased mine from my local Snap-on dealer.
Thanks for watching,
-Mark
Great video. Very well put together. Honestly I knew most of that info, but the way you put it, just made even more sense. Good job!!!!
thanks for such interesting video. These videos are an excellent marketing tool for your company. Please keep them up.
@spelunkerd We had a saying at the small engine shop I used to work at. "Everything gets a plug!". It would cost the customer less to simply replace the plug rather than starting a time consuming diagnosis. If the engine still won't run then we would pull out the spark tester. The tester I used in the video can give a false positive like you mentioned. There are other types though that can be grounded to the engine block, bypassing the plug.
Thanks for watching,
-Mark
awesome, clear explanation. very helpful.
Really good video! Very pedagogical! Keep up the good work!
Very well done and informative. Thanks
You teach very well
I have very poor hearing, and I found your video very clear. Also instructions were clear and straightforward, a great help, thank you!
Pat Nugent Since retiring, I have been fixing things that are broken. My sons are supplying me with various tools they own. Chainsaws, air compressors, weed eaters. I helped my oldest son fix an electric dryer and when he saw how simple it was, he has helped fix a couple for his friends. With the new smart phones (I don't own one) you can just get on CZcams and punch in an appliance and most likely they have a video that will diagnose and tell you how to repair it, while you are standing next to the appliance, it is amazing! I fixed a non-working NuWave oven (cost $150) for less than two dollars!! Amazes me how many people throw things away that are fairly simple to fix. But I realize not everyone has the same interest or talents.
Steve Schuller so do you have the rest of the deck I am missing? Many say I ain't a playin' with a whole deck.
W-40 is the best starter fluid for a two-cycle engine,with out risk of blowing it up or scoreing the rings,FYI,Good Video!
Thanks for video. It is very easy to follow and very useful.
Excellent tutorial , thank you ...
