It's a manual choke carb, and I have the screw all the way out for the choke. Normally when I slap a carb on first time after a rebuild I turn the idle screws out 1.5 turns each, bottom out the idle speed screw and turn it in 2 turns, and bottom out the choke so that nothing is in the way of the idle. I get it running and adjust timing / idle speed / mixture screws to lowest idle (usually shoot for 700-800rpm) and then set the choke (if it's electric) after it cools. Normally works well. I guess with all the trouble getting it started and replacing the coil I should just reset everything and start over. Probably just out of whack from trying to keep it running!

So anyway back to the topic, anyone have a known good tune for the 1407 on a 402?
