If you were to change the float chamber cover for a fast flow fuel type (Pinasco, DRT & Cosa) With the 5.2 float needle and drill the carb fuel channel, would the jetting need altering as I’m sure I read somewhere it may run rich ! With my limited knowledge I can’t see how this can happen, so any thoughts appreciated.

I did that Hotdog, plus a fast flow tap but didn't need to alter my jetting.
