Hi seeking ideas on how to fix a Kohler 15hp which is backfiring - it's just commenced backfiring , only occurs when the engine is warm at idle/standby revs after throttling down.
Everthing else on the engine is fine & it runs apart from the backfiring faultlessly (i.e no oil usage, no leaks, no "rattles" & it remains easy to start), regularly maintained & always run on "fresh" 95 or 98 non ethanol fuel - currently @ c.420+hrs ( originally out of a JD LT155 wreck with unknown hours & has done 420hrs driving a water pump for me).
Thanks
