My 856 has a motor out of a 1206. Bought this wrecked 1206 three years ago, the parking brake did not hold rolled down a hill and a oak tree took one rear axle off the tractor. The motor had about 2000 hrs on last overhaul. My 856 motor had about 14,000 hrs on it and was past wore out so I bought the whole 1206 cheaper than a motor overhaul. The problem I have with this motor is at low rpm, under 1200 it wants to miss out like a gas motor with a plug missing out.I had the inj pump rebuilt last summer but did not change anything. It also smokes black like crazy. Even sitting idleing smokes black and put a load behind it and no mosquitoes for miles. It does not have the power it should have. My 806's will walk away from it with the same load. Could it be the injectors not spraying right and letting fuel just run in? Anyone have any ideals? Does not use any oil or run hot under load.
