466 motor issues May 27, 2014 06:43AM
at the end of a pull last year . my tractor lugged way down then started missing. it was putting raw fuel out exhaust manifold. and if you tryed pushing throttle a head fast it would like flood out. but if you went slow it would wind up. i tryed pulling and no power. tryed different pump. had injectors checked. any thoughts.? thought timing was off. checked all that. crank gear seems to be in the same spot.

Sounds like you might have a couple of spun bearings.

If you are running a stock head are the valves stock? Your valves maybe warped. If you are running with a lot of heat you may have valves that are not sealing.
