I bought a NOS 5171 kit from someone on here and I don't know what jets equal what horsepower. Does anyone have this kit and if so what jets are you using for 75, 100, 125, 150 shot. If no one knows then I'll just have to sit on hold with the people at NOS. Also do you have the change out the shim in the regulator when changing jets or is it the same for all. Any help would be greatly appreciated.
