First, how many hours can one expect to get out of Champion REM 40E plugs in a cherokee 140 0-320 160hp?
Also, I went to fly this morning and when I switched to the second key position, the right mag, the engine was a little rough. Running it up and leaning it out would clear it up, but it would come back. I didn't go fly. I am having the jpi 730 insatlled today, so I guess I'm needing to have the plugs cleaned also. What do you think it could be?
