You are inserting the feeler gauge between the rocker arm and the top of the valve stem? Just above the spring?? :wrench: Click to expand... Yes between valve stem and rocker arm.I set the clearance to 0.010 and a 0.011 is tight but 0.010 slides through when cold. After replacing the plastic cam gear and faulty ignitor it's a different motor,has more power.
