Hello, i've just aquired (but not collected) a mid 30's stuart P4 two stroke. It is a bit different as it has a gas carb on it, i was told it would have been for town gas but now is calor butane. It looks 100% stuart turner original and has a oil tank and drip feed oiler and big brass dial/mixturelever (?). Can anyone tell where i might get some imformation on this unusual carburetter? I have a P5 manual but it doesnt mention gas. I am also interested to see how the oil gets around as being on gas it has no petrol mixture to carry it around the engine, hmm.

Thanks

I got a P4 Manual but it has nothing on the gas engines.

I have seen a Picture of a odd p3, but that was running on petrol, but it was quite strange.

The Stuart Turner Info Exchange might be able to help?
