@@dmrcflyr2 i have bought used saitos, and found the push rod improperly install. the lifter end of the pushrod can damage the rocker arm adjuster screw by wearing out the socket shape opening and cause the push rod to come out of the adjuster screw.
@@dmrcflyr2 The depression in the tappet where the pushrod inserts is too shallow (in my opinion) and as the tappet wears the pushrrod won't stay in the depression. I could have rectified it with a new tappet but that was another problem in a long list of problems with this engine, so I gave up on it. To be fair it was a very high time engine. The valve lash has to be accurately set at .002 - .004" or else the tappet wear is acceleratred. I have a Saito 62 and a 72 both of which are excellent. Be careful when buying an engine with a questionable history.
Make it a third Saito with the pushrod jumped out of the tappet. My 56 began to do that and got progressively worse until I gave up on it.
What can cause that besides being timed incorrectly?
