[QUOTE="westgl, post: 95279, member: 2025"] I bought the 32DFT from a company, that was started by a retired Fuel/carb. Engineer, that designed and worked for GM. Tom is the engineer, he now has his own business, one of the things he sells is this Weber 32DFT carb. they are Brand New carb.s Not rebuilt, for $90.00 ea. It is surprising how it looks identical to the 740 carb except for the Venturi size. The 740 is a MotorCraft/Ford Holley, Weber carb 24/25 mm progressive, used on 1981-1986 ford Escort/Lynx engines 1.6L The 32DFT is a Carter, Weber Carb 32/32 mm Progressive used on Ford Fiesta 1300cc OHV, & Escort XR3 & other vehicles, it was made for small engines, look at that Ford Fiesta 1300 OHV sounds close to what we are using it for size wise that is. Weber, must have taken something that was already proven and made a different sizes. There was also a Weber 32/34 that also looked like the 740 & the 32dft, Observations: Looking down into the bore's/venturi's from the top of the carb. past the choke plates, These two carb's, The 740 & the 32dft looking into the Venturi's, I forget what they call them. This part reduces the venturi bore size down, to a smaller than venturi size, after the Choke plates, but, before the throttle plates at the bottom of the carb. designed to speed up air flow, by reducing venturi size, (they were replaceable in different sizes on my Weber 48IDA carbs) both 740 & 32dft are sized very similar on these bore reducers, but the venturi throttle plate size is obviously different.
