Rich on 1 and 4?
« on: July 27, 2011, 09:57:24 AM »
After fine tuning the carbs, I still run a little rich on 1 and 4.

I am suspect a weak spark instead of a carb problem? Since they share a coil it would make sense.

Yes......I would look at the ignition system first. If it were 1 &2 I would check for fuel delivery. You could have bad points,coil,or bad connection. Could be out of time  but you're right about going for the ignition before fuel.
