I do not run alky but im very familiar with it as I have many friends that run it. If I was ever to switch to alcohol, my winter process would be as follows:
Take my alky carb off, put on gas carb. Drain alky out of the fuel tank by running the fuel pump and disconnecting the regulator lines from the carb and directing the alky into the fuel jug. Fill fuel tank with race gas, fire car up on race gas, get the engine nice and hott, at the end of the heat cycle, shut fuel pump off, while engine is running and have someone spray a bunch of fogging oil into the carb, preferably "foggit". Shut car off after being fogged. Drain remaining race gas out of the fuel bowls and pump the rest out through accelerator pump into a rag. Open throttle blades, spray more foggit into the engine while someone is cranking the engine. Close throttle blades, crank engine some more, done. Next would be change the oil after the heat cycle on race gas.
As far as the alky carb, I would spray foggit into the fuel bowls as well as throttle blades, or wd-40. From what I have been told and read, the alcohol really becomes corrosive when the alcohol is exposed to air. A lot of people I know dont drain their fuel bowls in between weekends and keep their fuel cell full to avoid any air getting to the alcohol and causing extra corrosion. Some of this is coming from Chris Baer from APD. He goes as far as taking spark plugs out of his engine and spraying fogging oil into the cylinders that way. He also puts race gas in his alky fuel bowls after a race so that the car starts easier next time, and so that its more resistant to corrosion from sitting. A lot of that is during the season type of maintenance, but for the winter, I would be doing the above listed method. Before the next season I would rebuild the alky carb and replace, needles, seats, floats, accelerator pump diaphram, etc.
Just my 2 cents.
Love your Demon by the way!
