What size allen wrench does it take to adjust the vacuum advance on a stock dizzy out of a "77 F150 with a factory 460.
I just want to take a few degrees out of the vacuum advance as it pings a bit with light to moderate throttle (about 10-12" vacuum). Full throttle is OK.
Also, which way do I turn the wrench to retard? Righty tighty?.....
Thanks in advance,
Tom
