[QUOTE="DaleH, post: 476317, member: 15636"] PLUGS - The 1st thing I always check for hard starting is a proper plug gap. Use only Champion plugs in that motor and gap at 0.030” regardless of what another gap spec (typically 0.028”) you might see, as OMC made the change years later. FLOODED - The recipe for flooded OBs is to close the choke & start at highest RPMS in neutral, just be ready to immediately back off the throttle once she clears and fires. OTHER - Some motors are like women ... YOU need to find out what SHE wants to start up & turn on. Maybe that OB needs a little more throttle in neutral to start up after being off for a while? You say you have the OEM manual, do a sync & lync and check for where the roller cam is. [/QUOTE]
