I would have the dealer check out his engine and find out what is going on with it.
If he wants to replace it with a Kawasaki it can be done also, we use the 19, 23 and 25 hp on the Fastrak and FasTrak SD series.
My 27hp Kohler manual tells me to shut it off at near 1/2 throttle to avoid backfire. It has a auto fuel shutoff or something. That is what causes the backfire if shut off at low throttle.Might be the same for the 19 hp I don't know.
