I will try and adjust the pedal linkage tomorrow. When I looked at the linkage, I realized the lever was NOT all the way against the WOT stop screw. With a hand held tach and a piece of reflective tape on harmonic balancer and a helper holding the throttle wide open, no load, only seeing 1800rpm- versus spec of 2375rpm. Refilled with Rotella T6 5-40 same as what is in the engine- makes it easier to start on 0 degree mornings. Took the drain bolt off alos to get the rest of whatever liquid it was out. Opened the injection pump oil level bolt- what looked like rusty WATER came pouring out almost smelled like old stale gasoline. Had the engine idling and raised the rpm slightly and depressed the lever- did NOT induce a smoke show. Click to expand.Loosened the shut off cable, worked it back and forth and pushed the rod in- still pops out.
