this might sound Craaaazy, kids. but from my reserch late into the night last night, 32s and 34s are made from the same castings, the body is the same, and I watched a guy bore out 32s up to 35.5... yup. and I also read some imfo on boreing them out with the hole offset up OR down for different outcomes... hmmmmmm. depedning on how they look chucked up in the lather or on the mill I might be making some carburetors totally worthless lol..
