I have a 150cc engine it was riding grear. But Monday afternoon when I took it out to go for a ride its started up as normal, I was half a block from my house when my engine turn off. I had to push it back home. I took the head cover off and it looked the the valve keepers were off a bit. So I took the rockerarms to have a better look. It turns hour to be that the keepers fell out of place. I put them back and it started up great but an hour later it turns off again. And when I everything apart, the keepers were off again. I put them back again and this is my 4th time douing this. They juat keep falling off. What could be happening. Can someone help me fix this problem. Thank you very much.

You probably need new valve keepers, look at them the grooves inside are probably worn and not holding and fit loose and will pop out. Best to get new ones because they may fall down past the valves and damge your piston or flop around and fall down by the chain and then into your crankcase where they can do some damage as well.

There are to half moon shaped keepers and only one fell off put that's enough to make it loose compression.

I am surprised that a valve didn't slip down far enough for the piston to whack it.
