Carburetor

[stebec]

Merry Christmas everyone, I presume that the carburetors on my 1975 spitfire 1500 are the HS4 type, is there any markings on the carburetors that will tell me?, the only number I can find is this one.

Thanks

Indeed so: FZX1258 was the HS4 for Spitfire 1500 and Dolomite 1500 years 1976 - 77.

Off the top of my head I would have expected a 1975 Spitifre 1500 to have the AUD665 specified carb; not that that's much of a difference - plain jet as opposed to the later Waxstat jet. Waxstats can be problematic and are often disabled or replaced with the early jet.
