Re: Posa idle adjustment
My experience with the Posa leads me to the following comments regardingtoggle quoted message Show quoted text
1. Disconnect your linkage from the carburetor slide and see if it is
actually closing all the way. It will appear to be closed when it isn't.
Close the slide and see if your linkage hooks up with out moving the slide.
2. It sounds like your mixture is still too lean. If you enrichen the
mixture it will idle slower. That may also explain the lower static rpm.
3. DONT try to fly it with only 2700 rpm static. You need to see 2950+
4. I have found that I need to aggressively lean the mixture after engine
start to keep it from loading up and therefore hesitating when full throttle
is added. I keep it leaned until I push the power up for takeoff. I also
find that I need to lean it on long letdowns to keep it from loading up. If
I don't it will balk on touch and go's or a go around.
5. Also make sure you have the carb heat butterfly open when running it
up. Otherwise it will run rough and at a lower max rpm.
That's my 2 cents.
