Skep419, where are you at this point?

1 turn out on the idle mixture screws, and (I'm assuming) still a stinky idle? And since you only have 1 turn on the idle mixture screws, I'm assuming (again) that they're quite sensitive?

You might go beyond 16* initial timing just to see if the engine likes it. Don't hammer on it b/c you'll have too much timing at higher RPM, just putt around the block and see if it helps.

If the idle is still rich after that, it's time for larger Idle Air Bleeds and/or smaller Idle Feed Restrictions, as previous posters said. Long term, both of these mods require drilling and tapping on your carb. Short term, you can install a properly-sized wire in the IFR to partially block it. Shout back if you're interested, as there are plenty of people here who can walk you thought it.
