Jim,
Good to read about your flying for the crowd. Are you still using a
Posa carb?
Three weeks ago I bought a KR2, N26LT. I ran the engine (HAPI 1835
with Posa carb) today for the first time, it ran nice. After running it for
twenty minutes at a variety of power settings, I checked the valve lash and
compression. When I pulled the plugs, they were black and sooty.
I read Jim Faughn's article from December 2001 on fixing the fuel
needle. I found it on Ryan Young's webpage, with his diagram.
This is the first I've worked with a Posa carb -- I'm an auto
mechanic and farmer, I know something about carbs, both simple and
complicated, and I'm willing to work with this carb, not convinced that I
need to replace it. But I am a newbie at it, and I don't have any paperwork
on the carb that I can find. And I sure would like to be able to adjust the
mixture in flight. I'm told the builder of this plane leaned the mixture in
flight by slowly shutting the fuel valve off.
A couple questions:
Jim adjusted the profile of the main fuel needle, right? Are "supercarb"
modification (that allows in-flight mixture adjustment) plans available?
Jim, you don't have this, do you? Other advice for me now?
Thanks,
Rich Meyer
