All things I have been considering. The fuel tank is pretty much level with the barrel. I think it's within 3/8" in but I will measure it later. The fuel tank basically sits in the formers so there is no insulating foam. I will try to sand it out and put some foam in. I was also thinking about the pressure the high speed needle runs at about 2 full turns out. I was thinking about blocking one of the holes from the pitts muffler to see if that would help. Any more advice would be great.

Thanks
