Re: Briggs and Stratton push rod and clearance
The lighter pushrod should be the intake side, and the heavier one should be the exhaust side. You can double check by looking at the rocker arms where the pushrods go into them. The clearance should be 4 to 6 thousandths on the intake, and 6 to 8 thousandths on the exhaust side. This should be done with a completely cold engine that has set overnight as the tolerances are pretty tight, and heat can affect the clearances.
