Reviewing ancient writings of Racer. Working on this motor has me baffled, can't get it to idle smoothly, it backfires and stumbles. Timing light shows steady spark with no fluctuating. 3 cylinder. ID tag worn off, but boat looks original, owner said is titled as 1994. Rebuilt carbs, changed head gasket, compression 110, little lower on upper cylinder. Top carb had wrong main jet....#34. Replaced with #45? Can't figure out how this happened, also all 3 floats were installed upside down. Original stator and original trigger but brand new CDI power pack. New non oxy dispensed direct with 6 gallon tank. New spark plugs. Tested trigger and stator with CDI tech live over the phone. Degreed and confirmed timing and tdc on flywheel. Tried another brand new CDI power pack yesterday. Same problem. Been at this outboard repair for 57 years, this is puzzling. No Alzheimer's yet. Any suggestions?
