Ed, It is interesting to note that the Curtis-Wright rotary engine had=20
the long axis of the throchoid at about 45=B0 with the plugs on the high=20
side! Semi plugs up. The exhaust port was near the bottom. So your way=20
of thinking has support. I've never thought plugs up was bad, just=20
certain people do. You do have to have a better fabrication ability=20
than conventional installs. the lack of available equipment is the=20
biggest drawback.

Good point, Bill. Mine will slowly leak down through the pressure=20
regulator, but not fast enough to preclude potential flooding with a=20
leaky injector. But in my case, "Plugs Up", any fuel that enters the=20
combustion chamber simply drains out the exhaust port(on the bottom)=20
and since the plugs are at the highest point, there is less likelihood=20
of any liquid gas entering into the spark plug cavity and drowning the=20
plugs. This is the reason why flooding is not a significant event for=20

One item of note is if your EFI uses the small orifice bleed to prevent=A0
vapor lock the system will depressurize. This will prevent flooding=A0
even if one of your injectors has minor leakage.=A0
