Subject: Re: Needles for 2" SU carbs
Bit late replying to this but may be helpful to anybody looking now or in future. I have 2" carbs and went through a number of attempts to find the right needles, including having flats filed on the needles installed; all trial and error. Put the car on a rolling road with computer readout (Stanton Motorsport) and see exactly what is happening. Needles chosen accordingly. Result: Heavenly relief!
