I am working on an Exmark mower and the serial number plate is missing. It has a Kohler Command SP 23. The serial number sticker is missing on the engine too. 1 cylinder has 150 PSI compression and the other has 90 PSI. Engine does not smoke and does not use oil but has no power when put under a load. The cylinder with the low compression turns the plug very dark black. We are thinking either head gasket or rings. But we can not find a model number to order parts. I called Kohler help desk and they said the do not make a Command SP 23. But that is what is on the shroud. Any information would be helpful. Thank you in advance...
