I am currently resealing a 94 ezgo marathon. It has a 295cc. Cam seal blew out of head and was leaking oil everywhere. I put all new seals on it crank balancer shaft gasketts ect.... I put it back together and it's binding in the bottom end every time it reaches tdc. With the side cover off rolls over with no issues. Put the side cover back on and it binds every time at tdc again. Upon further inspection the crank gear looks like it has a couple dents on the teeth along with the balancer shaft. Like somthing went through them. I can assure you it was not like this when he backed it off the trailer I heard no strange noises. Rolling it over by hand upon re assembly there is a very loud clunk every time it reaches tdc. I try to mark these things when I split the case but the balancer shaft was stuck to the side cover when I removed it. Is it possible that they re timed the balancer shaft a couple teeth so that the bad teeth didn't mesh up?
