Hi everyone, I recently noticed the oil level rising on my JD 300 Industrial and figured it is likely due to the injection pump shaft seals. I installed a complete seal kit, governor ring and a new pilot shaft bushing. Before removing the pump I pulled the valve cover and inserted the timing pin in the flywheel making sure the front-most cylinder was at TCD. After reinstalling the pump the tractor starts and idles well but doesn't rev up much when moving the throttle lever, it just emits more smoke out of the exhaust as if it is getting additional fuel but not accelerating. I ran it with the cover off the injection pump and manually moved the metering valve to the full throttle position to make sure it was not a governor issue but the result was the same. I've removed and disassembled the pump again and don't see anything wrong but I am certainly not an expert with these. Any suggestions would be appreciated, thanks
