Orma, As you probably know, I am running an EFS-2 on my 2700 Corvair. I absolutely love the Ellison. When I installed it and hooked up the Facet fuel pump, the engine started right up and has not hesitated any since. It is not a gravity flow and does require pressure to operate. As Mark L mentioned there is a suction port which allows the internal regulator to function. Now, I did not have to pre-suck the EFS-2 to start the engine as one has to do on the EFS-3. I simply hooked everything up and started the engine. The only adjustment I ever made was the idle mixture and I have a sewing machine idle at 650 rpm and have max static of 2750 rpm with a Sterba 56x64 wood prop. With this set up, I hit 50 mph on the runway doing a taxi text at about half throttle. I was so surprised at how fast the Corvair got the KR to 50 mph that I never looked at the rpm since I was concentrating on reducing the speed before the lift from the stub wings got me airborne. Go with Ellison, you will never look back.

This Ellison is sold with a Rotax attached. Can it be converted and used with my Type 4?? When you turn the fuel pump on what happens, does fuel start to flow like the gravity flow revflow? Or, will it only flow with the mixture lever rich and the throttle open? Do you think that the EFS2R has the same jetting as the EFS2. Lastly, what makes you, or how do you know that the Ellison is actually better then say the Revflow. Now I know this is a loaded question and expect a great deal of opinion. Keep In mind that no matter how good the metering is in the carb, I plan to send the mixture through the turbo and into my home made induction system. So if I can get the same amount of fuel out of the Revflow why should I go the bother of changing the carb? > > Orma L.
