Not a bad idea Patrick, but I'd be inclined to doubt it would do much good. The problem with the Carter is the neoprene accelerator pump will be damaged when it dries out (after exposure to the ethanol gas). This means your pump might only last a few months. The problem with the Rochester is the power piston will wick fuel up into the gap between it and the air horn shaft and this will dry as a sticky varnish-like mess. Given time, it will cause the power piston to stick in the down position, and I have not observed that it will correct itself. This will make your carburetor run as rich as it possibly can. Also the ethanol won't do your accelerator pump any favors, either. So either way you're sort of goosed. The best of worlds is to drive them or start them often enough that your carb doesn't dry out, but I realize that can't be done by everyone. Personally I'd avoid the Rochester in this case, get a Carter and buy a few replacement accelerator pumps so you'll have them as needed or try one of the ones being sold on eBay claiming to be resistant to ethanol (they are orange in color and have a fiberglass web molded into them). I don't know if they are as good as they claim to be, but it is worth a try, I suppose.
