Idle 52-140 - Turned idle up, mixer screw all the way in, backed it out until it no longer affected the rpms, lowered the idle.
AC140 - i was using a 120 up until today.
BE4
125mj
Starts up on the 2nd or third kick with no choke, maybe just a slight twist of the throttle, then idles by itself.
The throttle is very responsive, and crisp off idle, but once I start getting on it, I get sputtering/spluttering(sounds like its blowing a raspberry) through 1/4-3/4 or so. I havent even gotten it to WOT since im on 35mph city streets. The plug looks dark brown, and the air filter has fuel on the inside of it.
I don't mind running a little rich if it means a cooler engine, and less chance of a seize. This isn't a performance build. But the noise sounds like crap.
I was thinking maybe stepping down the mixer, since I have yet to hear anyone running a 177 with an AC larger than the 140.
Any ideas where to start?
