Im sure this is a very stupid question, but I haven't ever really had someone show me the proper feel for feeler gauges. Setting up the valves, I can get it so .004 slides in freely and has very LITTLE drag coming out. However, when I do that I can slide the .005 in with some force and it drags heavily going and coming. Same for the .006/.007 on the exhaust side. Which way do I need to set the valve up for? Am I just not tightening up the valve enough on the .004/.006 and need to go a hair more?
