I am helping a friend get his plane ready for first flight and we had to cancel today because the engine won't run reliably or smoothly at idle.
Details: Titan IO-360, Precision Silverhawk injector, EFII ignition.
Symptoms: Engine runs fine at higher RPMs, but dies when pulling throttle to idle with light backfiring and rough running just before quitting
Question, I figure the culprit is a misadjusted idle mixture. Should we go richer or leaner? I am thinking leaner. What ye think? Any other adjustments suggested?
