i could never smile as much as this guy while working on broken equipment lol...

@youngcameracompany 11 лет назад

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.

@Anhedonia411 9 лет назад

I love how he used Carb Cleaner as Starter Fluid. Learn something everyday.

@kittylovermybut 8 лет назад

+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.

@newcoyote 11 лет назад

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.

@rodneyjackson622 8 лет назад

This made me more knowledgeable about, how to fix my machine. I am thank fore for this timely information.

@brew4953 10 лет назад

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.

@Nifty-Stuff 9 лет назад

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!

@jimdidonato1246 8 лет назад

Nice job! Good pace, good coverage, and good shots of the equipment.

@bpekhoul 9 лет назад

Thank you so much for your explicit explanation. Excellent presentation. Thanks for unselfishly sharing your knowledge.

@johnthatcher5225 8 лет назад

This was just what I needed. I fixed my trimmer and leaf blower. Thanks for the valuable information.

@AWelter750 9 лет назад

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.

@stevefoxon6742 8 лет назад

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.

@tminceb 6 лет назад

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

@BenKingEagles 9 лет назад

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. :)

@KabeloNgwenya 9 лет назад

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

Well done nice video a very pleasant demeanor . Informative steps in diagnosing a problem

@FIXTechGuides 12 лет назад

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

@hokieinidaho 12 лет назад

I found this video to be very educational the way you broke up the analysis into a systematic approach. Wish I'd seen this a couple of years ago. Great job!

@schmittenhammer 9 лет назад

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 RU-vid 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.

@ElementsBJJCanada 6 лет назад

@shadovanish 11 лет назад

Great video! On my weed eater, I experienced a low power condition with the engine, which was caused by a poorly sealing crankcase cover gasket on one occasion, & a carbon fouled muffler on another occasion. The poor crankcase seal resulted in low compression in the crankcase, which allowed the fuel air mix to leak out instead of going into the combustion chamber, & the carbon fouled muffler did not allow for good exhaust flow, thus reducing engine power.

@spelunkerd 13 лет назад

That's a really good summary, Mark. I was interested to learn that you feel a spark tester is a more reliable index of adequate spark than is pulling a plug and grounding to chassis, and watching for spark there. But what if the plug is bad? If the plug is shorted then I would expect a spark tester to give a false positive, since current is flowing, albeit on an aberrant pathway. I' e never used a spark tester like yours but I'll consider getting one after watching this.
