I need to replace the 22hp command kohler. I want to put the new 23hp kohler with the better air filter on it. Can you give me either the model and spec #'s or the kohler pt. # for this new engine? Also are there any problems in doing this or is it pretty much a bolt on procedure? My dealer doesn't have the engine in stock but a local distrubutor might. I need to do this today. Thanks for your help. P.S. Buying my sixth turf tracer next week. Great machine!!
