I do have the manual, timing light, and timing light plug and I have adjusted the timing accordingly.
I'm actually having a problem with dry fouling spark plugs. Let me start by saying the bike had a few mods done by the previous owner. S&S super E carb, python III pipes, mild cam, pingle pet cock, and single fire ignition to name a few. I've used both Harley plugs and NGK with the same results, after running through about one and a half tanks of good grade fuel, the plugs get black and sooty. I'm pretty sure I don't have a manifold leak, I did that test using WD40. I've adjusted the carb following S&S's instuctions, but the biggest improvment so far, has been going one size down on the intermediate jet.
This past weekend I readjusted the carb float level a little lower, so far so good.
I just thought advancing the timing a little might help. I didn't see the ADV behind the wires on the timing plate, thanks!
Anyway if anyone has any other thoughts on this problem, I'd love to hear.
Thanks, Don
