There seem to be a few different Schebler-looking carbs available for the TE-20 and TE-35 tractors.
I'm only interested in knowing about the Schebler carbs, not the Zenith carbs.
A short (and probably incomplete) list of the stock or model numbers for these are:
533969M91
181532M92
183576M91
194065M91
181644M1
S.69198
I'm primarily interested in knowing what was different in the engines between the TE-20 and TE-35 (or TO-20 vs TO-35) such that a different carb is required.
Besides possible differences in mounting-stud spacing, carb air-intake and manifold-intake throat diameters, was there a difference in, say, engine displacement that would mean that these carbs are not interchangeable between the 20 and 35 tractors?
What I am specifically doing is looking for the least expensive carb to replace the Zenith on a TEA-20. I see some of these Schebler-looking carbs available for under $50 and I know the mounting studs are slightly different and they might advertised for TE or TO-35 hence I want to know why they wouldn't work on a TEA-20 (after modifying the mounting holes).
