Timing supplied by this device. Points under rectangle cover on lower left. Gear driven off cam gear. I pulled it out and moved it a little to make the points close at TDC. There is a little external adjustment possible.
6/29. I removed this today and dismantled it.
It has a mechanical and manual advance (arm sticking up in back).
The cam which drives the points is like a bushing.
I removed it, and ground out an area the right size to open the points about 25% of piston travel. This will allow the solenoid to stay on 25% beginning from TDC. Then the remaining 75% of downward travel will allow the air to expand, releasing it's heat energy. Sometimes this works so well the exhaust valves freeze. What a thought. Can't wait to have that problem to deal with. The mounting for this housing also allows for some rotation, to adjust timing. Now the solenoid valves are driven directly through the points, which act as the ground. Before, the coil was energizing the solenoids.
I also removed the intake manifold and made block off plates. If needed later, I can drill out the centers and add barbed fittings to allow air in.

1/2" brass check valve on exhaust. I had seen a VIDEO ON YOU TUBE where someone had added a check valve on the exhaust of a converted briggs to run on air. It would only continue running with the check valve installed. Lee used plastic exhaust, and decreased it's diameter. His exhaust was around 30 degrees cooler than the air going in. That means the engine was using the heat energy in the air, nice, huh?

7/26/09. 550 Suzuki air fuel conversion.
Intake manifold (home made) could also be used for a single carb in a hydrogen application. Waiting for a 4 cylinder distributor to control timing of solenoid vales.

Exhaust pipes were cut off, and 1/2" pipe fittings welded on.
