Re: Engine problem
If it is a hydraulic lifter cam (and I'm almost certain it is) then there shouldn't be any valve lash...it should be zero. The hydraulic lifters do usually need some preload, typically when you reach zero lash turn the nut another 1/3 of a turn to 1/2 turn.
I think a lot of your problem is having no vacuum advance. I would try a VA distributor before I spent money elsewhere.
