I posted this in my other thread, but thought that maybe the title would keep some from even reading. So anyway, Ive been trying to get my Sonerai running with a cv40 but am to the point where I just need to get it back in the air. In that vein I ordered an AerInjector this morning. Hopefully it won't take too long to get here. In the meantime I am going to get the airframe/engine as ready to accept it as possible. so I have a few questions.
1. My previous carb required a fuel pump and the airplane currently has dual electric fuel pumps running through a spring type mechanical fuel pressure regulator. I read in the AeroInjector manual that my setup can be used, but from other AeroInjector users, would I be better off switching to gravity feed?
2. How sensitive is the mixture control system? My last carb had no mixture control so I'm starting from scratch here. I have a high quality locking push-pull cable but will I need a vernier type cable?
3. Does the mixture control have a spring to hold it open (rich), or does it rely on a stiff wire bowden cable to go to the rich position (ie: Don't use a flexible stranded cable.)?
4. Since fuel can run from the carb if the mixture control is not idle cutoff, I am trying to decide my preferred mounting angle. I could mount it angled down (up-draft) so that any fuel that runs out of the carb runs out of the throat, but then any fuel that runs out it is inside the cowl (possible fire hazard). If I put an elbow on and mount it horizontal (side-draft) then any fuel that runs through the carb will sit in the elbow behind the carb possibly creating a flooding potential. I'd like to hear how others have theirs mounted and their experiences.
Thanks John Brannen
