Throttle Cable

"Too long" = later upshifts (and earlier downshifts when you floor the accelerator).

The carb gasket should be approx 5/16" thick, not the thin 1/16" or 1/8" item.

That's interesting Bouchillon say their kit won't work with a 225/1bbl setup. I'd want to have more detailed info from them; "225/1bbl" is not a single setup, it's multiple different carburetors, multiple different kickdown levers on the trans, etc. Without knowing what they have in mind, I'm having difficulty guessing what the incompatibility might (or might not) be.
