Charlie, I hope that I did not. Have not changed the timing 12 Degrees at the distributor when 3X2 set up was on the motor. No pop back on that set up. The crankshaft advance was spot on with ISKY specs. If I had a manual choke I would try to change the air mixture with the choke blade to see what happens. I don't know what I can do yet with the carb pump arm to get more fuel if that's the problem? In this hot weather I am having fuel boil out causing flooding on restart. I have a fiber spacer to put between carb and intake but installed yet.
