I'm in Malmö, where in Sweden did you buy that flywheel removal tool?

I'm having a similar problem,,your a genius,I bet that is what's wrong with mine.,,, It still has compression.

Amazing people don't know it's called a sheer key always has been all small engines have them

Does this work on gy6 50cc moped scooter engines?

was this engine a zongshen one? i am having problems with mine 2. i also have spark,and i even got it so far as to idle for a minute,real crappy tho but it ran,l. but it wil not keep on running nd as soon as i gave it a litle throtle it stalled. i put new gas in there,and cleaned the carb en everyrhing,there is a new spark plug in there so that should be fine 2. i am just not so convinced on the spark part,because it is realy poorly visible so maybe not a strong spark? my quad is a zhenhua 250.

Great video… about to go try it

I have the same motor and the same starting issues . I will definitly check this on mine. Thank you

I killed mine, it stucked and fire has done the other part. Now its Molten XD but anything is good. Now i can´t buy a new one

I can confirm that I had the same issue, I replaced the woodruff key and it started right away, and also it started sounding like the engine was new, no popping, no backfire, more power, thank you very much sir

This didn't help me at all but I wanted to share the point of the comments people left. You have helped so many people by posting this video and that's truly awesome man Be the light Brian d

Thank you very much! I opened up the stator cover and removed the flywheel and my woodruff key was completely flat, managed to get it out and now I'm waiting for the new part to arrive, hopefully it will start now

Wood ruff key .. oh shit I drop it.... 😂😂😂

Does the flywheel will also fit to 200cc engine?

I have the exact same problem on my 125cc Lifan engine but haven't looked at the fly wheel yet. Thanks for posting this video because I am as stumped as you were. I feel for you. This bike that I put a 125cc on is my only means of transportation right now. The bike has been sitting for almost three months now and I need to get it fixed. I'm 65 and pedaling a bicycle uphill doesn't work.

What is the key called

Can you tell me where you bought the new oneway clutch? I have a similar problem but since I am supid i managed to damage the flywheel while removing it

Cheers bud I've been trying to figure out how to get mine off

Thank you! My side by side hasn’t started in 3 months… I have spark, fresh fuel and compression. For almost 2 years it has started just randomly and then for a month or two not started. I cleaned the carb (it was spotless anyway), changed the ignition coil, ignition wiring, cdi. I have tested and re-tested the coil, stator, crank position sensor, starter solenoid and the regulator rectifier. They all tested good with the multimeter. During all this time when it did run I would hear something still ‘spinning’ for a few seconds after I turned it off. My next step was to visibly check the stator. I just found your video today explaining exactly what may be wrong with mine. Thank you!

I watch the whole video you did a great job explaining

I'm going to the same exact thing now that I just watched this video at almost 1 in the morning I'm going back out to my shed and pulling my case apart to see if this is the issue because I think it is

Hale yea man ty now my little girls four wheel runs great again 🤙🤙

Thanks a lot. That was very helpful!!!

Thank you, would not start til I put flywheel key in right position for coil spark.

Muy bien explicado gracias.

Hi…. I am looking for the part you described as the “wood-druth” key? Can you provide the correct spelling of this part? Thanks…

iv just replaces my 1 way clutch , its has spark and fuel do u suggest taking fly wheel back off ? how do i know if the woodruff key is damage or if its another problem 🤷🏻‍♂️

Future reference for everyone coming to this video if you have air fuel and fire it is going to be an ignition problem Don't waste your time going through your carburetor or your coil go straight to the stator and I guarantee you will find your issue along the way of removing it. 99.99% of the time timing is always the issue in these cases. Good luck to everyone I hope that helps

Starts 3:10 No offence to the channel, everyone does this, I just wish people get right to the point in the first 30 seconds, then go on and on and on about all the things that they messed with that weren't the issue.

Thanks for sharing

Thanks 👍

Thanks for the video. But what if the woodruff key is confirmed correctly positioned, as well as valves adjustments?

you are amazing sire !!!

Alelulla...brother...thank u for your video

Thank you my guy so much for this tip I am a big moped tuner! But Mann I could not figure out why my girlfriend bike had great compression, big fat blue spark and I had done everything to try to resolve why I was getting no start! And then I found this video and it all made sense, so I removed the magneto to find a perfectly sheared woodruff key! Replace it and after the first kick it start up really strong💯 again thank you brother for this tip! I once told my gf not to lose tiny parts like that because even though it may seem like missing a few tiny parts would be fine, noo! Never knew such small component can cause such a big problem!

Your fucking amazing man you saved me

I have this same problem on my qt50 but am not sure if it's a sensor or something preventing it from turning over

I have a question, i have a eton 90cc. It has new wire harnesses, new carb, new stator, new starter, has compression but it won't start? It has spark, gas does go into the motor but still doesn't start... any guesses?

I have the same problem, I'm going to try this, thank you

brawoo wel l done😊

please man i need help with my bashan if i drive it in gears its hitting someting and does not wanna go in 1 gear nor nutral stuck in 2 gear but still driving in 2 3 4 5 and changing back to 2 gear

O shit bro i subscribe only for you energies to keep working on the bike i have same problem i already replace everything and have not spark im going to try that too bad i don't have a lot compression is that going a problem for spark?

When it finally started after months of agony I imagine you were a little emotional. I know that I would be. Thanks for sharing.

Do you need to put oil in the flywheel cover? And if yes wich oil?

fucking tming its wrong...just use your brain. Spark fuel air and timing

Don’t do Chinese 😴‼️‼️

I have a 250cc and replaced EVERYTHING it gets good spark but does not start at all

Very good .you never gave up ..i dont either i have same problem im about too check flywheel. Like your video .well done .

Could you use the same bolt that you take off ?

What is the thread on the flywheel puller? Is it special or normal thread

Great
