Converting A65 to A75

[Jim Herpst]

It will simply make more noise, burn more fuel and not achieve a thing. Stick with the 65 and lighten the plane all you can.

If you have the dough go to an 85.

waltermrich , looks like several people don't care for the A75 engine, but I wouldn't let the comments stop you from converting if that's your plan. If you do so please let us know how it turns out. I've got lots of time in A65 and C85 powered Taylorcrafts but have never flown one with an A75.

You can always do the modification, and if you don't like it put the 65 prop back on. I know of several A-65's that have all of the A-75 parts installed, but they still run it as a A-65. Turn it up to 2300 for cruise if you want to go faster. Just realize your fuel burn will be between 4.5 and 5 GPH.

That's what we ended up doing. Putting a 72-42/44 back on it and flying it like a 65.

On Harry Fentons web site on Continetal engines he claims the A75 carb venturi is 1-5/16 inch the main jet is #46 and the airbleed hole is #60 all of this in the C75 manual.same carb as A75

the A and C carbs were different, the A65-75-80 all used the same venturi in the stromberg
