Onan loses power

Posted by Jack at LL on February 02, 2005 at 13:33:42 from (63.204.130.70):

(I posted this on another forum, sorry if there is a duplication) Anyway, I have a brand new Onan flat 20 hp engine in a Toro Groundsmaster that will not pull a load when hot. Starts great, runs great for about 40 minutes, then bogs down, backfires and gives up. Will restart immediately, but won't take a load. I've checked valve clearance, compression, manifold vacuum, put on a gravity fuel system, everything seems OK. The only clue is it seems to be heat related, otherwise I am stumped. Any thoughts?
