I ran out of oil in the main resevoir tank and on the 200 the timing gets retarded as a safety to protect the engine. The reserve never went below 1/2 full.Now after priming the oil system, everything is fine up to 4200 rpm but it tops out there. It seems to be miss firing (but not real bad) With more than me on board it hardly gets up on plane. This also lead me to discover my warning system isn't operating. Is there something I'm supposed to reset after a low oil situation like this?
