This new 235 seems to be missing on the first cylinder, that is to say when I pull the first plug wire it makes very little or no difference in the idle. So I decided to set the valves, like I have done many times on the old 216.
It seems to me that there is quite a bit of springyness in the pushrods. I really have to push down on the rocker ends to get any sort of gap at all, even on the valves I know to be closed. So I am wondering if I might have acquired a 235 with hydralic lifters. I don't have any experience with these.
I screwed out one of the rocker adjusters all the way and could see a hole in the middle of the pushrod end. But according to the numbers this is a 235 from a panel truck from 1953. The engine has had at least one thorough rebuilding. It has aluminum pistons and insert bearings. How do I know what kind of valves it has without pulling the side cover? (which doesn't leak!!!)
I did adjust the valves as if they were solids and the engine seemed to run better. The first cylinder still seems to have only the slightest effect on the idle.
