If you get your tuning right there is no need to do a pinch test. I never needed to use it....

thanks to the ones that helped. so i was right, thanks for confirming. I think i always had mixed results doing it right at the inlet. it always wanted to be lean pinching at the inlet. I never thought it was a good test because of that. makes sense as its so close to the mixture/air intake

Pinch testing used to be used as a 'ball park' not as a check, So no point in doing if your tune is right.
