Have one each "87 &'88 club car gas carts. Both have side valve Kaw motors. One has been re-built.. Thinking bout installing the 13hp item #66555 harbor freight motor in one on an experimental basis, just see what's involved.. Anybody done this have any info to share I would surely appreciate.. This 13 hp model is a CCW motor so I dont have to run it in reverse as it seems some ofher folks must do. It appears it will physically fit with gas tank, muffler, auxilary pull start etc in place, althiough any or all of this could be removed and be plumbed up seperately.. Guess main thing is will stock clutch fit the 1' X 2 7/8" on this 13hp motor? are there any other major problems??? THANKS LAJim..
