Re: I hate 4 Strokes

[Don]

Don’t have any knowledge about these engines, but I know the cam timing must be verified or the engine will never run right…Do you have the proper service manual for this engine? The correct manual is absolutely necessary for clear set up instructions. I’m not sure just how your cam is driven. I guess I am used to the smaller 4 strokes where the cam belt is driven off the flywheel and comes out on top of the engine to the cam gear. Kind of sounds like this is not the case on your engine. If not, the cam gear is concealed inside the engine and driven off the crank.
The slightly damaged key you pictured would not affect timing all that much unfortunately, wish that was your problem though.
I’m hoping someone here is familiar with your engine and can give more concise instructions….For now, stick with the basics like Mumbles says, fresh fuel, proper oil level, and recheck compression once the flywheel is properly reinstalled.
