Check your shift interrupt swi

Check your shift interrupt switch.Prob came out of adjustment when you took the drive off.Make sure the switch nipple is in the valley when in neutral.

"Ross,
I had this same problem last week. My 87 MCM 180 cranked and cranked but wouldn't start. After verifying that the shift interrupt was in the correct place I checked for spark and found none. I pulled the distributor and cleaned and reset the points and it fired up right away and runs great. If you have a conventional ignition system I would try this to see if you can get it running.

Good luck.

Easy check just push the actua

Easy check just push the actual switch down and crank. 98 out of 100 times it IS the shift switch.
