I recently had my 01' engine rebuilt because 1st and 2nd gear went. I built it back up, and just put the oil / coolant in today. I have yet to try to turn it over and I ran into a problem. I was checking to see if it shifted smoothly and everything seems fine besides it won't go into neutral. I've adjusted the clutch so it'd engange 100% and tried it at a couple different spots. I cannot get it into neutral for the life of me. Does anyone have any idea what it could be?
