Yeah, Ive done the measurements and I will have to do something in order to fit the cowl. Eiter I use shorter standoffs with a hole in the firewall for the carb or I move the entire firewall back by an inch or so. I asked Chip and he said that he cut a hole in his firewall. He also mentioned that the lomger standoffs were sometimes hard to keep tight. I got a machinist buddy so I'll prolly just measure them to what I need and let him whip me out a set.
