the engine will idle well at 78 psi but if i go down to 75 it stalls out...but if i go up to 120 or 150 psi it does not idle up or anything i think that is due to the compression resistance problem i am having... they already have cars that run on compressed air over in europe... i am going to rebuild a briggs and straton 3-5 HP engine, make it run on air, and put it on a dirt bike for my senior project (we have to do that to graduate). but i have to mess around with the cam shaft so the intake valve will open on the down stroke and the exhaust valve will open on the up stroke, and also figure out how to keep like 300-400 psi into a tank.
i will try putting it on the carborator side and see what happens
