"Dan, how do you prime the Ellison, with a can of primer? Larry Bell"
My GP 2180 with the Ellison is primed with a normal aircraft prime knob. Two or three squirts with a cold engine and it has always started instantly. Hot, it needs no prime. With Steve Bennett's top-mounted manifold fuel distribution is excellent. When I had the heads off about three years ago to put in new valves & springs the combustion chambers were all a very light tan, equally colored. The Ellison has a mixture control and I use it, however on the Ellison site it states the Ellison TBI automatically leans as altitude increases. I've always flown the plane up high where I see full throttle operation between 3 and 4 gallons/hr. It's a shame they quit making them . . . and now Dan says the EFS-3A is also no longer in production? What a shame. There's a product from Australia equivalent to the EFS-2, made by Rotec. I've never seen one but it appears to be an Ellison copy. Price is around $1200 with shipping. It's nice not to have to fiddle with the carb or worry about the engine dying on a low final (although I still always do). Since I got my plane from Steve in 2006 I've never had to touch the Ellison. The EFS-2 is perfect for the 2180.
