Because this was the # plug that the motor came with n the plug I ran the 1st race with.......fast forward to yesterday changed bearing and put in a #5 plug suggested by a motor guy. Fire it up! Running just perfect now! So now I'm not sure if the bearing fixed the issue or the plug! Have you guys seen nova engines that just want a #5 vs a #6 plug?
Chet, with as cold as it is up there now, the 6 plug was going to be hard to tune. Plus you run your motors too fat(the excessive oil is why the front seal blew off your bearing) The hotter plug burned off more of the residual fuel and oil and gave the impression that it fixed your issue. If you started out by leaning the motor out, to get away from all the extra oil and fuel running through the engine, you might have been able to get the 6 to work.
There is a reason I always start tuning your engines by leaning them out. You are relying on fat tuning to keep power in check, but you should tune them with a clutch or venturi instead.
Motors hate to be run extremely rich, just as much(sometimes more) than being run lean.
Mini me is always trying to hook you up. You should let him sometime. The kid can tune a motor.....
