The EC2 instructions say 36 psi. I only moved = it to 42-43=20 psi to get some usable mixture range for the short run today. My=20 Aeromotive is missing the adjustment screw and was reading 30 psi out of = the=20 box. We installed a temporary screw and tried 36 psi. It was better but = still=20 did not have a very wide mixture range on the rich side. Once I put the = prop on=20 I will set the pressure back to 36 before tuning. I need to verity how = my=20 primary and secondary injectors are setup first.

That's interesting. When I was first = starting to=20 test my rotary I had to back the fuel pressure way down to get it to run = relatively well. I'm backed off as far as the Aeromotive regulator will = go and=20 indicating about 33psi. Now that things are running better maybe I = should try to=20 bump it back up a little. I think Dave Leonard told me he had to go down = on=20 pressure as well. What is the consensus opinion?

Still some little tuning issues but = it's running=20 well enough to taxi around now. Runs great above 3000 RPM. Maybe a = revisit=20 to fuel pressure will help.

Need to find a DAR and get this thing=20 inspected/flying!
