I'm in the process of building a dune buggy, but I've hit a bit of a bump in the road. I'm trying to pull the motor out, and it just won't budge. I've removed the 4 nuts that hold her to the transaxle. I started by putting a jack lightly under the motor and pulling on her gingerly - an approach I soon gave up on. After a lot of pulling, a friend and I managed to get it out about a half inch, but it just won't come anymore. The only explanation I can think of is that the spline on the transmission rusted and caused the clutch to stick on it. Has anyone faced a similar problem?
