Hi just put a set of new Amal Premiers on the Spitfire as had odd carbs previously and didn’t idle well (a 930 and a 932 !)
When starting cold have to really flood the carbs and choke for it to start, but then needs choke on even when cold or warm to rev cleanly from idle.
Tick over with or without choke is fine. It’s the initial throttle response that is poor if start to rev with out choke. It sort of fluffs then picks up.
I’m guessing it’s too lean on the pilot jet ? Will need to check what’s fitted. Has 190 main jet and needles are on the middle clip- am I on the right track ?
