Larry you are correct. I got rid of the fuel pump for gravity flow alone before I ever got the plane out of the work shop. I have a fuel pressure guage and the header tank keeps the areo carb happy all the time between .7 # and 1.2# Joe Horton

Sunny skies , light wing pretty much down the runway. Unfortunately the air was rough at pattern altitude and not so comfortable flying. I decided to just smooth out the landings. The Cruzer is such a light weight , high drag airframe that it loses speed in an instant at the flare. I'm modifying my approach to carry a bit more speed and a touch of power at the flare. The throttle in this airplane is so touchy and rpm change is instant that its hard to fine tune power. The first approach went fine in to the flare and as I came in with power I got too many rpm. The airplane leaped back in to the air and rather than trying to correct that close to the ground I went around. The second approach was more steady and made a safe landing. I'm suggesting to the builder that he install a Vernier throttle control to smooth out power changes in the flare. I think we'll get this pony saddle broke soon. It sure doesn't fly like a KR or even a Cessna. I hope to test fly a Zenith 601 in the near future. It has a small Lycombing engine, 0-235 ir 0-290, not sure which. I think he is getting it inspected in the next week or so. His only problem right now is with an "Aerocarb". It ran fine on first engine run but now it fires up and quits. This would normally sound like a fuel problem, not enough fuel, but in this case I think he has too much fuel pressure and it is flooding out the engine. I think that carb only requires about one pound of pressure and he has an engine driven pump and an electric pump. I'm guessing, without seeing the engine and setup, that he will need to install a pressure regulator before the carb. A friend years ago had a similar problem with a Harley engine on a 601 and a pressure regulator fixed the problem. We shall see. Keep building everyone. You have no idea of the fun that awaits you.
