Default re: EZGO 295 - 350 engine Valve Adjustment

The adjustment should be made when the engine is cold. As the head heats up, it expands, increasing the gap between the valves and the rockers. the expansion of the head moves the rockers away from the valves, the steel valves will not expand as much as the aluminiun head will..... so the gap gets bigger when the engine is hot.
I don't think .004 more lift will make a whole hell-of-alot of difference on the robin engines, but then again I don't use a gage when I adjust them, I just back the screw up a 1/4 of a turn.
