Carbs - F1 or F2?
Spitfire:
Pretty sure the inlets are bigger on the F2.

Your F2 had F1 carbs cos the F2 PD type are abysmal

DO NOT fit new jets just ultrasonic all the old stuff, aftermarket brass is not always accurate

Unfortunately, I do need to replace the main jets at the very least - it's been fitted with 115s instead of the standard 105s. I'm not sure why (to compensate for an air leak, perhaps?) but I don't have the originals anymore, either way.

Really that bad? What makes them so unpopular, out of interest?
Irritatingly, I actually have *two* sets of F2 carbs - one built up, one in pieces. Guess that ruins my plan of trying to sell them... ;D
