Check fuel tank vent in cap, I had a 6080 that did the same thing and that's all it was. It wouold run like it was starving and I suppose essentially it was in a vacuum and couldn't get fuel.
when we stop the oil stayes in the rear reservoir,infact the rear reservoir is full!!!! so i would say that it doesn't have that mod as to the engine if we slow down it will pick back up. i treated the fuel when we put it up last fall,checked the lines and filter evan drained the tank and refilled with known good fuel
what year modelIJ only the 78's had to have the kit best I can remember. When the reservoirs were tied together on the hydros the cap for the rear tank had a plug in the top with a fitting for a hose in it. Then the rear tank stayed full.
Did you check your air filterIJ Did you put on a new fuel filterIJ My F2 would run good for about a hour than would slow down. I would replace the fuel filter and it would run ok for about a day than act up. When the motor got warmed up enough to warm up the filter the motor would slow down. Never did find the over all problem and did not have the problem until the next year.
Dennis, The clutch disc part n for the seperator clutch is 71302902. I am not sure if you are looking for the bearing that is in the carrier for the seperator clutch engagement or a bearing that is in the transmission clutch assy. If you are looking for the bearing in the seperator clutch carrier then that bearing part n is 71115513. If this is not the area you are looking for let us know and I am sure that we can get the correct part number. Hyper Harvest II
