En passant as they say, the number 32 is a reference to the choke diameter. So it is that the smaller engined Tractions usually have a 32 PBIC carb. Perchance you find a 34PBIC scudding around, this is the definitive carb for the 11D engine. Worth trying on to see if it makes your engine a little more “urgent”.
