OK, the engine leveler works great! Except when you ask the help to lower the rear of the engine, the help turns the crank the wrong way. Does anyone else have that trouble?

I am having trouble getting the engine to slide in the last inch or two. Is there some trick to getting it in the last couple inches? Maybe the splines aren't aligned? Maybe the transmission and engine aren't lined up properly? Maybe the clutch isn't lined up properly?
