Subject: Re: Needles for 2" SU carbs
Peter, as an example the 3670cc Aston Martin straight 6 in the DB4, fitted with 2 HD8 uses UN needles in 0.125 inch jets. I see the Daimler used UB for a twin set up on a 4500cc straight 6, and UL on a twin set up on 4500cc V8
I wonder if the Bentley 4800 cc 6 cylinder might be the closest analogy to your LG6, using UC or UD needles?
Also do you have copy of the SU needle profile chart ALT9201 which is said to have advice on choosing alternative needle profiles
