I have a problem with my Lycoming engine in my 9A.Engine is an IO-320 with Airflow Performance injection and dual P-mags timed 2 teeth past tdc.I’m running 91 octane non-ethanol auto gas.First 2 hours the engine ran and idled fine but now the idle is very erratic and wants to die if throttle is pulled back too much.The exhaust pipes are black on the inside which makes me think it’s running too rich.I tried leaning the idle mixture by adjusting the linkage 2 flats but it doesn’t seem to make much difference.Am I on the right track here or is it something else? Thanks. Dave
