Hey Bigbud, Look for a good used Briggs or Tecumseh or even a Kawasaki. Good used horizontal shaft engines are getting scarce and a bit pricey because most equipment built today went to verticle shaft engines, but still cheaper than new and they can be found, it just takes a lot of scrounging. I find it a little easier, simpler, and cheaper to adapt mower engines, a throttle and choke cable, a battery cable goes to the starter through the start solenoid, one wire to ignition kill, alternator wire goes to battery terminal on ignition switch. I used a fuel tank that when installed, the bottom of the tank is the same height or slightly higher than the carb to make sure fuel gets to the carb whether it has a fuel pump or not. The only other problem is you would have to find a driver clutch that would fit or adapt the existing one. I figured out a way to adapt verticle shaft engines to my 84 & 89 EZ-HOs because I had the engines on hand plus my older carts are fairly easy to modify to make everything fit, but we won't go there. LOL! Hope this helps a little, good luck. Bob
