Default Re: 1998 - G16 valve adjustment specs

Compression stroke, ether thumb over spark plug hole while turning crank or watch intake valve close as piston comes up. At the top of that stroke, is TDC. Adjust valves with piston in that position, .004 feeler gage snug, draging it between rocker and valve stem. You'll get some power if they are off even a few thousands, and a quiet running motor!!
