Fellow near me put a rebuilt unit on tractor and couldn't get it started. When pin goes in flywheel pump timing mark is just out of window. Said he left shaft in tractor and lined dots up on slot. Looks to be one tooth off in front. My question is there enough room inside the cover for pump drive gear to get out of mesh? Also says it's pumping fuel. Thanks
 
It "sounds like" they did everything correctly..
I'm assuming they tried to turn the pump to line up the lines??
IF so, I'd say it moved..
 
Yes the pump won't move enough to line marks up. He failed to line pump marks up before removing, so hope it's on compression stroke for # 1 But pretty well has to be if he lined up dots and didn't get something way off. Going to remove pump, think drive gear can be moved a tooth and tried without removing front cover? Notice I spelled injection pump wrong in first post. Thanks
