Vapor Carburetor

Hi Lee,

I switched to Shellite (Coleman fuel) to avoid the problem with the volatile fractions in petrol (gasoline). The same thing happens with my old motorcycles - the fuel tank sits over the engine which is still hot when I stop. This evaporates the volatile fractions and makes it hard to start next time.

Yes, I noticed the cooling of the tank as well and it does make a bit of difference. Holding in your hand helps until your hand gets cold. Then comes the hot air gun.

Like you, I use it first up because it is simple and usually works enough to check the rest of the engine. A whiff of propane is also useful, as is Aerostart (marketed in Oz as "Start Ya Bastard"

Built 3 versions, using Coleman fuel. First worked well, second had rotary valve, and was difficult to find good settings, third (latest?)has external air screw adjust and works fine on all three of my engines.
