Lot easier way to do it.

There are two logical "formulations" that, when both used, gives a practical working solution for an "independent" motor starting from a common gas-line. A common gasifier delivery line usually (in a good system) keeps below 50 cm H2O. A motor with tight valves, without overlap and hidden crankcase ventilation into the manifold develops ~ 500 cm H2O at cranking. Combined with the fact: Identical pressure drops over identical openings (slots) results in IDENTICAL FLOWS. (with similar fluids) Using identical ganged twin flaps with identical geometry for gas and air will deliver a 50/50 air/gas mix, if starting both from atmospherical pressure. The secondary air intake pressure has to be regulated to equal the momentary gas-line pressure with a membrane and air-line flap, sensing the resulting air-pressure versus the gas-line pressure. This way the total pressure drops in both "legs" will constantly be equal. To furthermore assist slow crank starting, the twin-flaps will be closed by a trimmable spring closing the flaps COMPLETELY. A manifold-vacuum membrane or cylinder, diameter ~2-3" opens the twin-flaps when the spring starts to give in for a vacuum of ~100 - 200 cm H2O. This opening increases as the motor fires, and has to be controlled by a manually settable stopper = idle limiter! When fired, there has to be a "change over" to automatic run...

I think a check valve in each fuel line would be needed but would it be a problem to get the second engine running? My system would consist of a charcoal gas producer with two 6.5hp engines.
