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.
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.
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!
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
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.
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
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.
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 RUclips 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.
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
@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
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
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, 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. :)
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.
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.
As a processional small engine technician with over 50 years of mechanical expertise I find this video to have some flaws in your two-cycle troubleshooting. Due to the limited space allowed I cannot post them all. Overall though I have to say it is a good video even if it is still incomplete.
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
The most likely cause of this would be low compression due to worn piston rings or a worn or damaged cylinder. Start with a compression test. Anything less than about 70psi would be considered low. Hope this helps, -Mark
Great video! What am I missing? Echo PB 200 blower. New spark plug and strong spark with Oppama tester, new carburetor, fresh gas 50:1, new fuel lines/filter, compression = 90+, spark arrestor clean. Get a pop with starter fluid, but can't get it running. Already bought a new one, just the challenge of trying figure this one out.
Duane Miller check you carb adjustment screws, or check the needle valve for proper operation. sounds like your not getting fuel. also if its an older model exhaust can build up soot from running improper oil mix clogging the muffler seen a few but not that common.
Thanks, Raguel Bauman. I agree, has to be a fuel issue - just can't find it yet. Gonna go back out there right now and go through the whole fuel system again.
Well done a lot of the help videos I see on RUclips are filled with umm and it might be... but this has definitive answers thank you for your quality video!!
I have a question about the spark tester, since it is inline with the sparkplug one must assume the sparkplug is new. I have here a sparkplug that is wide open when you measure it on a ohm meter and I thought my coil was bad.
Excellent! Got right to the point, but left me a bit confused as to what is indicated by too much compression. I'm guessing that could be friction/pitting from running too lean a mixture or gummy residue buildup?
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!
First thought would be a plugged spark arrestor. See our video titled "How to Clean the Spark Arrestor on a Small Two-Cycle Engine". If the arrestor looks good then you will likely need to rebuild the carburetor. Take a look at our video titled "How to Rebuild a Two-Cycle/Two-Stroke Engine Carburetor". I hope this helps, -Mark
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.
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! :)
i have a troybuild weedeater it starts fine and idles but as soon as its revved up it cuts off i have replaced lines, line filter, primer bulb and spark plug also new gas also cleaned carb checked muffler for clogs sso what now?
It has been the case with me that I have experienced many fuel delivery system failures never requiring a carb clean or rebuild. 15 to 1 my issues are in gas filters inside the tank, fuel lines or primer bulbs. You might want to add a word about them. It just a thought.
That's a great point! We're always open to suggestions from our viewers, and we put out brand new videos each and every weekday. Thank you for the advice, and don't forget, you can subscribe to our channel and get access to all our new content, some of which based on viewers like you!
Hi Mark, I think your videos are very intelligently presented. I have a question. If the engine starts when you spray starter fluid into the carburetor, then isn't the carburetor okay? Doesn't that mean that the problem is the delivery of the fuel TO the carburetor that's the problem? Thank you.
Good video. But what about the crankshaft seals? You can have good compression, but if the crankshaft seals are worn, there won't be any intake of fuel mixture into the crank housing.
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.
Great info ,I own a stihl brush cutter and when I give it more throttle it doesn't seem to cut off or slow down,and when it starts the spool spins when I ain`t touching the throttle`so I adjust the throttle cable and it struggles to rotate fast and cuts out,any add vice please on these matter,owe yes I have checked the baffler and it seems it seems to be good,
i have a husqvarna 128 L D weedeater it is about 2 years old. . it will run for about 15 seconds on full throttle and then dies. If if leave it on half chock it will run longer before it dies. I thought it may be a vacuum problem from the gas cap vent, so i removed the cap completely and still have the same problem. It was running great until one day the spark plug became loose. I removed the plug and found the plug was loose in the center of the plug. I install a new plug and ever since i have had the problem. Thanks for the video they are great
Considering the $150- $200 cost of replacement it's unlikely I'm going in as deep as new rings on a little chainsaw, but your starter fluid, and a new plug is a $5 very doable pre hurricane field test ritual. Thanks
Hi Winston, here's a repair guide from our website that should help you troubleshoot your trimmer that runs for a while, then dies: www.ereplacementparts.com/repair-center/lawn-equipment/trimmer/runs-for-a-while-then-dies/ Good luck with your repair!
Thanks for the help. I have a Poulan 2150 chainsaw 36cc 2-stroke. Worked perfect 2 days then would not start the third. It appears to have spark and compression. Tried a new plug gapped to 0.020" but not a gig. I guess I will clean the carb, but starter fluid/carb cleaner did not work to fire it for even a second. The plug does appear to be wet with gas after I pull it a dozen times but I will clean it and the fuel filter too. I guess if that does not work I will try a spark tester.
great video's i have a problem can you help with advice please fs stihl 120 strimmer no spark new plug , new coil ,regapped the coil at differn't settings checked the switch its fine tried with kill switch off no joy magnets are fine the only other thing i can think of is that the keyway has gone on the flywheel ! what's your assumption please , thanks .
You may want to check to see if the flywheels key is worn. Check the spark plug wire to make sure it has continuity. I looked up the specs for a FS120 and the spark plug gap is 0.020 . And the coil gap should be 0.12 . This is a long shot, the flywheel magnets may have lost their magnetic pull. We are not a Service Center for Stihl, so I am not familiar with them. It may have an electrical part that I am not aware of.
Thanks for the reply gapping on the plug & coil is correct the continuity is 2.6 @ 20k on the secondary side ,there is a slight play in the flywheel key which is cut out of the body of the flywheel would this cause no spark with being a small engine ? i once had a ryobi with the same problem ! my theory is the flywheel if you have a good coil! i dont know what else it could be , it was running but stopped the coil was bad , thanks

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

I have worked with 2-cycle engines for many years...But this video is most informative and helpful !!
Who's watching this 2020? Thank you, I'm fixing my trimmer, right now
This made me more knowledgeable about, how to fix my machine. I am thank fore for this timely information.
Thank you so much for your explicit explanation. Excellent presentation. Thanks for unselfishly sharing your knowledge.
Nice job! Good pace, good coverage, and good shots of the equipment.
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
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.

Very good, clear speaking and the best school ever in youtube. That's simple like that!
great video, really helpful rather than guessing what the problem is.

Really good video! Very pedagogical! Keep up the good work!
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 the videos they are very helpful.
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!!!!
Great video.Concise and put in laymens terms.Thanks
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.
Well done nice video a very pleasant demeanor .

I suggest you service it at your nearest dumpster.

very useful video very good info and well explained
good video thanks i have a problem not mentioned my Husqvanra weed trimmer backfires when i try to start it ?
that is usually a sign that the timing is off.
Owiko7 what you mean? cos then I pull to start i get pull back, handle comes off and thats hurts a bit.. whats on chainsaw,.
yep and have now fixed the problem thanks
Thanks for the help. I have a Poulan 2150 chainsaw 36cc 2-stroke. Worked perfect 2 days then would not start the third. It appears to have spark and compression.

The plug does appear to be wet with gas after I pull it a dozen times but I will clean it and the fuel filter too. I guess if that does not work I will try a spark tester.
great video's i have a problem can you help with advice please fs stihl 120 strimmer no spark new plug , new coil ,regapped the coil at differn't settings checked the switch its fine tried with kill switch off no joy magnets are fine the only other thing i can think of is that the keyway has gone on the flywheel ! what's your assumption please , thanks .
You may want to check to see if the flywheels key is worn. Check the spark plug wire to make sure it has continuity. I looked up the specs for a FS120 and the spark plug gap is 0.020 . And the coil gap should be 0.12 . This is a
long shot, the flywheel magnets may have lost their magnetic pull. We are not a Service Center for Stihl, so I am not familiar with them. It may have an electrical part that I am not aware of.
Thanks for the reply gapping on the plug & coil is correct the continuity is 2.6 @ 20k on the secondary side ,there is a slight play in the flywheel key which is cut out of the body of the flywheel would this cause no spark with being a small engine ? i once had a ryobi with the same problem ! my theory is the flywheel if you have a good coil! i dont know what else it could be , it was running but stopped the coil was bad , thanks
