When I first got my slant six, I went through two carbs in the first two years because I was running ethanol gas... the floats just fell apart, fuel level in the carb was thrown off and passages got gummed up. Definitely learned my lesson and started only going to stations that carried non-ethanol gas... some of them around here have ethanol in every grade they offer. If you don't mind a carb rebuild, best to upgrade to brass or nitrophyl floats.

What's the issue you're having with the choke, though? It shouldn't fully close during engine operation (you have to let SOME air in), and it should really only matter when the engine is cold. Once the engine is warmed, it should be fully open and then you find out if you have any other problems with the carb. The really old ones use vacuum pull the choke slightly open at start up using a piston which can gum up or fail. The better ones use U shaped pull off link which you need to adjust when tuning your carb to get proper start-up choke - although the vacuum diaphragm that operates this U arm can fail - when mine went, I found just this part of the carb at NAPA and didn't have to replace the whole carb. The choke is connected to your fast idle cam, so on most carbs, it won't fully close unless you pump the linkage once - part of proper starting procedure on a carbureted vehicle. If your choke isn't going from mostly closed to all the way open at the proper rate as the engine warms up, or closing properly as it cools, suspect the heat sensitive coil spring is worn or bent or it's not getting heat from whatever source it's designed to - air from the exhaust, coolant hose, or electric heater - the spring is either in a choke housing on the carb or in the case of my 77, directly on the engine or exhaust manifold.
