Engine 613477-2186-g1 447 hours Mowing in heavy stuff for 20 minutes and the engine stumbled and stopped. Would not restart until I shot starter in inlet. After that it started fine. The engine isn't idling correct hear puff occasionally . I checked valves .005". Put on new gas filter. Plugs few months old no buildup. Went back out to test and it pulls fine but just not running smooth.
