What is the difference in a Super H carb and one off a 300?

D Slater · Jan 20, 2019

Little different idle circuit and other metering for gasoline models, 23/32 venture in the SH and 25/32 in the 300. Two gasoline carburetors used in a 300 were different 361525R1 and R2. Rare to find a R1 now. Tried to spell venture different but spell checker kept changing it.

Venturi. Ignore the spell checker.

also the choke setup, SW4 has the wire rod and 300 has a cable.

Same choke shaft in SH and 300 carburetors. Just different ways to move it.

cant be the same part # , so its different. only the shaft is the same.

All I was referring to was the choke shaft is the same and can be used with a cable or rod. SH and 300 carburetors are the same size outside but bottom and top castings are different on the gasoline type.
