I have not purchased a manual as yet and would appreciate it if someone could fill me in on where to find the timing mark in order that I can adjust the valves? Any pictures would help out also. Thanks

 

Think there is a removable plug on the right rear part of the engine, where you can view the T mark on the flywheel. I usually just take the spark plug out, and as slowly as possible turn the engine over with the recoil rope, watching the intake valve open and then fully close, then carefully put a long screwdriver through the spark plug hole til it contacts the top of the piston. continue to slowly turn the engine over until the piston is at the next TDC, using the screwdriver as a TDC gauge. If you go past, you will have to turn the engine over two times before compression stroke comes up again (or as before, just watch your intake valve). Get it as exactly as you can this way (err on the side of just past TDC) and it's plenty adequate to check valve lash.

 

The timing mark cover is the hex-socket head bolt right next to the recoil starter handle.

You do not need to remove anything to access it.

 

Thanks guys. Do you need to remove the fuel tank to access the exhaust valves? Thanks again

 

Yes you do need to remove the tank, and a whole lot of other stuff, to get at the exhaust valves.
