Yes, initial timing means next to nothing if you rarely run your engine below 2000 rpm.
But for those that do, 20 deg initial, 38 deg total by 2600 rpm works great for me. I did try a stock setting of 12-14 deg initial and 38 total and it sure did not run well in the lower rpm ranges, may have been able to tune it out with jetting, but when I went back to 20 initial, it ran like it was injected car. I do not know why weber IR carbs like a lot of initial timing. Anybody have a theory? I have zero pre ignition with 10.5 compression and 87 octane fuel
