'77 230 valve clearance
Trying to adjust the valve clearance, it is way to tight there is no gap, and there are marks on the bottom of the cam lobes where it rubs the rocker arm, compression is way low, I think valves are sticking open.
I can't seem to turn the adjust screws. Could this mean they have been adjusted as far as they can go?
Thanks for any help.
