B&S 5hp engine suddenly runs slower?
My Craftsman Leaf Shredder powered by a B&S 5hp engine (model133412) runs great for 30-40 min then suddenly slows to close to idle. NOTE: I have to keep moving the CHOKE lever to keep the engine running. I removed the CLEAN air filter (NO change), and the gas cap. Later I removed the carb fuel bowl. It was clean. The next day started and ran great for about another 30 min, then as before it slowed to close to IDLE (not changing the throttle position).
