hi every one I am in the process of installing a pony motor back on my D4 and am having trouble getting it to sit all the way down. I am guessing the gears are not meshing together. Any helpful hints would be great, Thanks!
rotate the flywheel slowly until the gear teeth mesh (you may need to lift the engine a little while doing this so it does not turn both gears).
Also there are two lineup pins to keep engine align so you may need to wiggle it a little to get the pins in line with their holes in order for the engine to set all the way down.
