I was wondering if anyone had any suggestions on carb mods to help increase mid-range power for dirttrack / iceracing? I have a suppertrapp exhaust system and a k&n air filter. I'm currently running a 50 pilot jet and a 168 main jet. I have a works connection fuel air screw adjustment I do a little tweaking on from time to time to help the rev off idle. Any ideas or suggestions would be appreciated!
