I have a scag with 19hp kaw engine. Cranks and runs great with clutch engaged. When cutting it cuts great for a while, then sputters, losses power while backfiring through exhaust. Boggs down, then rpm picks up and levels out until you load it with another heavy cut. Then the symptoms reoccur. Have changed plugs and fuel filter. Any suggestions?
