1906 Bing spirit engine vapouriser how?

I've had this lovely little Bing four stroke hot tube spirit engine in my possession for quite some time now and thought it's time to make some steps into it's restoration.
I need to know how the spirit vapouriser works? Is it similar to the Daimler/Benz type of vapourisers for Petrol(Gasoline), this is when the air intake draws air through the vapouriser bubbling it up through the petrol so forming a gas?
Is spirit basically Methylated Spirit?
I hope this interests someone into giving me an answer!!

Hi Mike

I'd have thought that the spirit would be some derivative of methylated spirit or some basic hydrocarbon like methanol or some other crude distillate, its unlikely to be anything highly extravagent, otherwise the engien would have cost too much to run,
