Kohler Magnum 20 in Sunstar

Recommended Posts

I have a 1986/87 Sunstar with the Magnum 20 engine. I know that this engine is no longer available, though some parts are. right now it sounds great, was well taken care of, and I am replacing the ignition module.{just because the wires are extremely cracked from heat}Is there anything in particular that goes wrong with these engines? I want this to last a long time because re-power kits are :O $ I already have the owners and service manual for it. It also states that you need to run 5w30, or 10w30 in the winter, and MUST use straight 30 weight above 40 degrees. anyone have any coments or suggestions? Thanks for any input.

Keep plenty of oil in it. Also would put fuel shut off valve in gas line. It may not be a problem with the Sunstar, but in my 7117 , I have had the cylinders and crankcase fill up with gas.

I have the same tractor that I bought new and have run 30wt oil in the summer and 10w30 in the winter with no problems. Parts are readily available. Keep the cooling fins clean. How many hours on your Sunstar?

      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
