Finally got this B-450 tractor started. It has the direct start BD264 engine. So far I have done a complete valve job, surfaced head, new rings, end gap in cylinder is .010 cold. Used pistons with no ring groove wear, and new rod bearings. Injector pump cleaned all pumps, valves everything. ( uses inline style cav pump) Pumps well. Injectors dissasembled cleaned and pressure set at 1650 psi (also tried at 1500 1750 1950) this pressure has least amount of smoke. Cranks off of glow plugs easy but SMOKES SEVERLY-WHITE SMOKE and has raw diesel coming out exhaust. Does not miss but does not hit hard either(slight difference in each cylinder when I crack the injector lines) NO BLOWBY from breather. Running out of ideas here any help
