Clutch not engaging

[RenoRider]

So heres the story. After A LOT of other problems solved by searching the forums here... more and more arise.

So I was riding with my friend. and while riding, the clutch disengages seemingly randomly. At first, I notice that I am losing power, so naturally I turn the throttle a little. I hear the engine revving up like a car in neutral, but notice no power reaching the tire. I try this once or twice more and finally give up, and pull over. I pedal and try to start twice from the side of the road, and it just sputters and dies quickly. the Third time the clutch seems to be dead. and by dead I mean; The clutch will not engage at all. I no longer have to pull the clutch to pedal the bike.

And since this is my first post, i can not post links to pictures.

I opened the right hand side of the engine, and the little flat head screw part on the bottom right of the clutch box will rotate, but the sprokets inside refuse too rotate. Any ideas?

My roommate and I have struggled for the past 2 weeks on this bike project. When one bike is fixed, the other creates a new problem.

take the side off that has the engaging arm and see if the pin and ball bearing behind it come out. Inspect the arm to see if it is seated properly and the retaining pin holds the arm in. Are your cables binding?

You broke the key in there....if the big flathead screw will turn, but neither gear will turn, is broken.

update. So I went in to see if the woodruff key was the problem. and well, I guess it cant be a problem is theres no key there.

SO. I know the problem, i know i need to buy a new one, put it in there, and should be good to go.

BUT what happened to the old one? I dont know if it fell out once of the few times i took off the cover, and I just did not see it because I didn't know what I was looking for, or could it still be in the clutch or even worse the engine part?

The key is so small and when it got sheared, it got even smaller so it could be there but it's not a big issue. I would not be surprised if they forgot to put one in at the factory.

It was running for a good quater to half mile, then hit a small incline, then just POP. the key broke, slipped out, ect ect.

[toytime]

That's why I doubt you even had a key. Make one or get one from any place that sells small engine parts

[RenoRider]

What is the correct key size?
