We have met the enemy, and he is us!  LolMine also disintegrated, and the particles were ingested by the engine.   Seems a bit ironic for an air filter to expire this way, though oddly just for failing to replace it.   You too were punished.   Karma. Glad it worked out. Dave  Sent from Mail

So that pretty much narrows it down to Fuel or exhaust.  Have you checked your mixing elbow to ensure it is clear?  Restriction would certainly keep the revs from going up. After that it likely gets expensive in either fuel supply (high pressure pump/low pressure pump) or injector issues. --

You should also try to rev the engine with it out of gear.  If it has the same problem of reaching full RPM then fuel and air delivery are nearly to only possible culprits. A bad or weak governor spring would be indicated by an engine that has a tendency to over speed or hunt.  Pulling the
