Keith,
What I do is use my T-handled allen wrench to guage when the piston is TDC.
Just slide it in the spark plug hole (being sure you don't get it at an
angle and jam it in there DUH!) and turn the timing nut with a big wrench
back and forth till you get to TDC.
At TDC of the compression stroke both valves will be closed that there
should be .006 play on the intake and .010 on the exhaust.
I always start on the left side and them move to the right side when I am
done. I pull the spark plugs out of both cylinders so the engine turns
easily.
Good luck....after a few times it becomes second nature....Ian

Question is, book called for top dead center of the piston on that side being adjusted. Problem I had was at top dead center, I could not get a feeler guage in at all. Book also said that the valves should be fully closed on each side (inlet/exhaust) so what I had to do was mildly turn the engine until I saw one side completely relieved of contact, then checked and adjusted the valve. After that adjustment, I had to return the engine so the opposite valve was relieved of any contact, then made that adjustment. Is this OK? In this situation, the piston was not really at top dead center but was off a bit. The right side seemed to work OK, though the exhaust valve adjuster had to be backed out all the way to achieve .010 inch clearance. The left side was a bit more difficult. I repeated the same process as described above, exhaust valve wasn't a problem, but inlet valve was darn near adjusted fully out also, at that point, the piston really wasn't too close to top dead center, but it had to be that way to get any type of clearance on that valve. I'm a bit confused. Help! Did I do this right? I can't imagine adjusting the valves at top dead center as I had both sides adjusted all the way out and got no clearance until I turned the engine a bit and watched the rocker arms give the valves a clearance.
