Re: Stuttering Stanley

Thinking about all that carbon build up are all the valves free floating and not sticking ?

I had a 70 short box 4x4 that had lots of carbon buildup sticking two valves i had to replace 2 broken rockers was after the second rocker broke i realized the issue nothing a hammer could not fix on the side of the highway tapping the valves until they moved freely
