but yea trying to figure out differences on 223 and 220. I know the carb insulator material and numbers on head. Anything else anyone know ? Thanks
I believe back when the 220 was a thing that they were using the original 21j carb and the 223 was using the 21j3 carb. Not sure the differences, one of them is that insulator material but not sure if that is the only thing.
