clintonnut 126 #1 Posted June 24, 2013 Well, if you have an RJ or Suburban that needs a Clinton 1200 series motor, this is your final chance to reserve a beautifully rebuilt motor! I'll be going to college in mid-August so I will not have a chance to do any more for a while. Most rebuilds consist of: Sandblasted block/sheetmetal New crankshaft New valves New piston/rings New Connecting rod New Crank bearings New Gaskets Rebuilt ignition Rebuilt carburetor New Air cleaner New Starter Resurfaced tappets Mildly Ported Block bored Valve guides reamed oversize and new seats cut Kill Switch wire installed New spark plug wire It takes me on average 20-25 hours of my time to redo one of these motors and $100 worth of machine work to bring the block back to specs. They run like new, look better than new and will be a great addition to any vintage Wheel-Horse! Cost of a rebuild is $475-$550 and I will buy an old engine core for $50-$75. I have done over a dozen of these engines to this quality of work and you will not find a better rebuild anywhere! I own an RJ58 with one of my rebuilt engines and it has been in use since 2005 (2 of those years mowing a half acre every week) and it runs just like it did on day 1. I ONLY HAVE THREE ENGINES AVAILABLE!!!!! I can ship anywhere in the USA on your dime. Here are some past rebuilds I have done: And as always, I have a full inventory of NOS parts to build these motors and support the hobby Charlie 3 Share this post Link to post Share on other sites
clintonnut 126 #2 Posted December 2, 2013 Its been a while but I'm in the middle of rebuilding three of these engines. The first one has the shortblock assembled most of the way and the other two are being bored and valves oversized right now. This one is bored .020" with oversize valves. Plan to paint in two weeks, bench test and sell. YOU WILL NOT FIND A HIGHER QUALITY REBUILD ANYWHERE ELSE!!! Aside from the porting and polishing I do to the intake and exhaust on each block, I also polish the beams of the new connecting rods to increase their strength by eliminating stress risers in the surface.

Fordiesel69 199 #4 Posted December 3, 2013 Nice looking engine. How do the compare to the kohler for sound / durability / power? Share this post Link to post Share on other sites
clintonnut 126 #5 Posted December 3, 2013 They are very similar. The Clinton is a more powerful engine and it has a bigger cylinder bore and a longer stroke than the kohler. In regards to durability, they last just as long especially with a full rebuild to better than OEM. Share this post Link to post Share on other sites

VinsRJ 721 #10 Posted June 2, 2018 Hello, the pics supplied are spot on to what is needed for a Clinton throttle set up except all of the motors are missing one critical part. The little spring between the governor arm and the throttle plate. This spring is needed in order to keep the motor from hunting around for the rpm desired... 1 Share this post Link to post Share on other sites
