Re: 1972 Cheyenne 350 Engine problem
Timing was checked and at 6 btdc, I don't think my thermostatic air cleaner works...no vacuum hooked to it. Not sure of the gas, but you are right. A fill up of 93 is cheap and an easy fix if that is the problem. As far as vacuum leak, the idle is perfect. Wouldn't that ruin the idle and maybe cause stalls?
