Just getting done with the valve adjust. 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.
