Post by Gene_French » Sun Mar 15, 2026 1:00 pm

don't know what i was thinking BUT, i purchased a air compressor cylinder head for a model A motor ... thought this would be an interesting use for several used model A engines i have sitting around ... it is a simple reed valve assembly , i have tried to locate parts diagrams and a manual online , but have not found any useful info . , if someone here has a manual that could be copied this would be appreciated ...Gene French

I got one too. They pump a bunch of air. I would send pictures of mine since it is complete, but cant get to it right now.
I also got one made out of a jeep engine. It wouldn’t blow you hat off your head.
Mr Kemp had one with the trailer I think. Dan

Dan:
thanks for this link ... i am mostly concerned about the unloader configuration ... i have several model A Gleaner combine engines with the governors and carburators inplace , this would be a good base for throttle control ... the unloader valves are inplace on the cylinderhead , but no control valve ... will contact the club to see what they have available or have adapted ...there were several of these units around when i was a kid , i remember that they did move a bunch of air ...

The unloaders are controlled by a valve on the tank.
Common called an unloader valve. It send air to the unloaders on compressor to unload them at a set pressure and to load up at a lower pressure. The unloaders valve can be anybody’s make.
If that is your question. Hope helps. Dan
