How does timing affect the way an engine idles? Is there any sense in increaseing/decreasing timing to have the idle be smoother or choppier?
Right now I have it back to the stock 550 rpm (automatic 4 speed) with 13-14* of timing. I had it for a while as high as 750 rpm with 22-23* of timing and it seemed smoother, but less of an exhaust note.
So what do you guys run for timing and rpm, and how does it feel? Smooth, choppy etc?
