I would like to talk to someone who has installed and used a Ellison. I have my plane VERY close to being done and think that I may be running a bit lean. Reasoning is when I go to idle cut off I get no rise in RPM prior to shut down. I have read the ellison tech data that I could find and I have reached out to Ellison with no response.
I understand it is just a spray bar, and that there is an idle speed and mixture adjustment. But one of my questions is, does the idle mixture adjustment affect WOT mixture?
Also any negative issues I have seen talk about inlet geometry. I have the large plenum airbox as ellison suggests the only difference is I offset the inlet to one side of the plenum to align it with the cowling, a small change I believe but wonder if anyone has any thoughts on this since the first time to test it will be first flight out of a 2000 grass strip. My concern being how badly do they run if the air inlet flow is a problem?
