I have had problems with Zama carbs running Gas/Glow. The diaphrams swell up and then they won't run right.

I am using an "After Run" fuel on all my engines; gas or Gas/Glow now. It is Coleman Camp fuel, with Sta-bil fuel stabilizer, and Pennzoil for aircooled engines at 20 to 1 ratio. I DO NOT FLY WITH THIS FUEL AND DO NOT RECOMMEND DOING SO. I run my regular fuel, whatever that might be, then when I am done flying for the day I drain the tank, put in about a half tank of the "Storage Fuel" mix and run the engine until I am sure all the flying fuel is burned and the engine has nothing but the "Storage Fuel" in it. I then choke it to kill the engine, and drain out the storage fuel.

I was having problems with diaphragms going bad in as little as 3 weeks on my normal gasoline only engines. Since using my "Storage Fuel" I have several airplanes that have been stored for 5 months and then flown with no problems.
