I've been a long time lurker and figured what better place to see if anyone has seen this before...
I didn't build or install this but I have an 0-360 C2E out a Mooney and it came with a MA-4-5 P/N 10-4164-1 attached.
It runs too rich and I aggressively lean it for smooth running in cruise. Strangely, when leaning it out at low idle the rpm raise is less than 50 as it dies, as it should be. It soots plugs, I only run mogas but they are not badly fouled.
I read about the Service bulletin SB258 for the tapered riser insert in the sump but it seems that is only an 0-320 issue. My combination has about a 1/4" lip all around (sump hole is larger than the carb outlet) and seemingly needs a tapered riser?
Does anyone have any thoughts on this? Engine seems a bit low on power. But nothing to compare it to.
I'll try to attach a photo taken through the #1 intake pipe. It looks at a round mirror that looks down at the shelf that the top of the carb creates.
Never mind seems I can't do that.
Thanks all.
Mike
