I have been playing the setting the timing on my 502 chevy,
I set the timing at 15 degrees with the vac adv. off this was
based off the chilton book for ref. after I hooked the vac adv.
againe the engine idle raised and then I lowered the idle to 1000 rpms. I have been reading other postings and I keep hearing about full adv. is at 35 degrees. Could someone explane and
did I set the timing the correct way?
