sounds to me like you are adjusting them, when on the up stroke of the push rods. And if you had the cam out, make sure the timing marks are lined up again..............CurtUgh this is so frustrating I’m trying to adjust the dumb valves right now. It it now building pressure but the rockers automatically got sloppy and loose. I think you’re right about the spring as the rocker seems to put a light pressure on the valve at tdc when. I went down to .005 and it is pushing air out but the rockers are sloppy like I said. Maybe .004?
