A65 to A75

[jgerard]

I'm sure this subject has been discussed before, I just can't find it.
The data plate on my engine is one of those blank sheets of metal that's been painted about 3 times and the only markings are A-75 and a S/N. I would like to open up the engine and carburetor (Stromberg) to make sure I have the right parts installed. My engine overhaul and parts manual shows the difference in A65 and A75 parts but I have no reference material on the Stromberg carb. I am looking for the proper info regarding jet sizes and venturi size for that carb on the A75. Also what is the scoop on installing and using a mixture cable?

A-65 to A-80

How much more difficult is to just go to the A-80 ? I think that would give me the voom I need to get out with two on board in the summer?

Also, anyone doing this? I mean any A&P in the tribe that will do this and if so about how much $
