Re: ef3000iSEB: fluctuating engine speed in economy mode w/no load

Well, I got tired of looking at all the parts laying all over the place so reassembled the generator for fear of forgetting how she goes back together.  I didn't find anything definitively wrong although as stated before, the exhaust port of the cylinder head was quite carboned up.  At one point in this generators life, the spark arrestor in the muffler completely clogged; shutting the motor down.  So maybe all the carbon build up being cleaned up will resolve the issue.  Additionally, I heard from one owner who had the exact same issue.  A dealership resolved his and said the cause was a loose rocker arm stud.  So while I had the head removed, I pulled the rocker arm studs and reinstalled with red loktite; then readjusted the valves again.  

Keeping my fingers crossed that this gets it.  If anyone has any additional feedback, I'd appreciate hearing.
