Re: Need advice tuning PHBG carby
Good advice thank you! I just studied the Dellorto tuning manual and I understand what you are saying about the needle.
There is no room for a higher notch on the needle but I could drill into the slide body a bit to lower the needle more. As for the cut away I am assuming you are talking about the angled cut at the back of the slide well this is 3-4mm high. There is no cut away at the leading edge at all.
I might try to lower the needle by 1mm and increase the jet size a bit.
