Well, I can't wait to get this engine running for you.

To use a regulator (which I have used before for tanks that are too high) the general goal is much like a pump but it is gone about a different way. Instead of pumping the fuel with a "fuel pump" the tank is pressurized and a check valve is inserted inline to the muffler pressure hose. Pressure comes from the muffler but cannot go out that way, this forces fuel out the fuel pickup line. Without a regulator it would likely cause the engine to be over rich. The regulator restricts the fuel flow to the desired amount ensuring a constant flow of fuel regardless of tank position. I think this might work for you as the 30 is a pretty small engine, on a larger engine a pump might be a better solution due to the larger venturi on the carb having less suction (negative pressue on the fuel pickup line).

The pump, of course you know how that works.

Cline or Iron bay make regulators - I have an Iron bay in my corsair (which I still haven't built yet since the replacement from Hobby People) with the Magnum 91 inverted. On the one flight the original had I experienced excellent performance in the form of a great idle and a great transition as well as good full throttle performance.

and of course I expected I would be walking out there with you - what color will this one be? Silver again?
