Sunstar Engine Swap

Recommended Posts


Got a project on a 1988-89 Sunstar Engine Swap, I want to swap a 1982 Craftsman GT-18-Horizontal  opposed Briggs Twin from what I can find it is a Twin II engine, into a 1988-89 Sunstar that had a single kohler 14hp engine. I know this is doable but wonder if I'm getting into a major nightmare. Anybody on here ever perform this task and how difficult is it.

I have decided to go with another 14hp Kohler Magnum, Seems to be the best solution, They have more torque then the twins and easier to maintain and repair. I would rather have a 16 0r 18 single but they are hard to come buy in good running condition, Thanks anyway to any consideration, I do need a 16hp briggs engine that will fit my 7016H Soverign. Anybody out there have 1 reasonable Email me and let me know the cost. Maybe a 16hp Horizontal I/C motor would work.  Thanks

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
