IM OPEN TO ALL OPINIONS AND HELP ON THIS. ENGINE HAS APPROXIMATELY 4400 MILES ON IT I BELIEVE OR MORE.
Best thing would be to get hold of an advance reading timing light. One with a dial on the back, so you can read higher than the marks on the balancer go. Then, after checking to make sure both your vacuum and centrifugal advance are in proper working order (about 16 - 18 degrees each, max), set the total advance to 40 degrees.
(Check what your timing is set at now, at idle, with the vacuum advance unhooked and plugged. Then what it is when you plug it back on. Then what it is when you rev it up to about 3,000 RPM and hold it there momentarily. Subtract the first figure from the 2nd, and the 2nd from the 3rd, to figure advance specs.)
If you hear any pinging, dial it back a few until the next time your gas tank gets pretty low, and try it again after you put in the next higher grade of gas.
