Did the Gas model have a different carburetor design? or was the venturi only changed to a larger size?

sorry for my lack of depth on the question.
I was tracking the evolution of the G226 motor and trying to see all the differences

Dr.Allis, Is there any benefit of having the Marvel over the Zenith carburetor? I'm assuming due to their age (like the 170s) that the gleaner E combines' 226s all had the Zenith carbs?

A 175 Marvel carb has a bigger venturi and air inlet horn (more HP) over a Marvel from a D17/WD45 or E combine. I myself prefer a Marvel over a Zenith because the Marvel is all cast iron.
