26 hp command issues
« on: August 30, 2009, 11:24:56 pm »
I have a 26 hp kohler command
The problem is when its warmed up and need power it pops out the exhaust and boggs bad.
I checked the spark and put new plugs in it did leakdown test and it checked good  did compression test cold and hot both checked good   cleaned carb checked fuel flow everything checks out
did i miss something???   it has a smart spark module could that be bad??

The Smart spark could be bad it advances the timing to give it the extra hp rating. You can disconnect the smart box and run it with out it will lower the hp to 22 or 23. I don't remember for sure how to do it it's been a few years since I did it but I know it will work. Someone on here should know what wires need to be connected together in the white plug for it to work.

Take the engine apart and change the camshaft for one that doesn't have a decompression set up on it, or you can remove the decompression set up from the cam that is in there and fill in the holes with a good epoxy. After that your good to go ;)

Is this a fuel injected motor?  Crank engine over and check valve lift at rockers. Some of these motors had soft cams and just wear down on the lobes.
