So apparently we've all forgotten how the old fuel mixers work around here with all the fancy fuel injection and such!
Anyway I swapped out to smaller jets last night and it definitely leaned out my mixture enough that the plugs aren't black anymore. Now my idle is a bit high and I can't back out the idle speed screw to correct it. I'm thinking maybe the mixture at idle is too lean now and causing it. I may get a jet between the two I've tried and see if it gets better. I also have a hesitation at about 1500 now that could also be from it being too lean. Balancing act I suppose.
