Okay, ya'll have me stumped now. This is the truck that sat 20 yrs cause the advance springs were broken. All I have done is set base/intial timing. Someone else metioned an octane rod or something. All I can tell you is it starts right up, has plenty of power, doesn't knock, and doesn't run on when cut off. Is there any where on the net that explains what ya'll are saying to check? I'm a little to young to have experience here
