Not much on the Net. Most of my info is from "Internal Fire" by Lyle Cummins, 
starting on page 118.

My wording in regards to the intake valve is missleading. There is an 
intake/exhaust (two in one) valve plus a rubber check valve. I would think 
that it would be possible for the valve to get tarry but they had to heat 
(pilot flame) the engine for about five minutes before starting. Also I sure 
that town-gas would not be as tarry as our producer gas COULD be. But it did 
need some tar for lubrication.
