Why is the TR3 plug gap .032 and the 4/4A gap .025? .....and if mods are added like using the the longer 4A intake manifold and exhaust header, does that change which gap to use or is it just a matter of experimenting?
Also...I think I read somewhere that the motor would perform better if the timing was set at 3/8" before BTDC? Is that 4 degrees BTDC or 8 degrees? OR is there a sweet spot in regard to timing for performance or are there just to many variables to say?:emmersed:
