Thanks

The weight on the decompressor is what de-activates it. Without it, I can be activated all the time. Fix it.

oh. I can't remember how those old ones work. Is there a lot of play after it's removed? Someone else will have to chime in...

Hi if your engine builder messed up the timing maybe the piston is fitted with the intake valve cutouts facing forward they should face to the rear of the bike
