Husqvarna 2348LS Riding Mower, 48" cut, Endurance Series
Briggs & Stratton 23hp Engine, Model 44L777, Type 1038 B1, Code 071227YG
I was mowing a few days ago and heard the engine sound a soft putt. Then, slowly the putt became a louder more frequent pop. At low idle, the pop cannot be heard. At mid throttle, the pop is soft and less frequent. At full throttle, the pop is louder and more frequent. I replaced both plugs and added fresh fuel. After running engine for a while there was no change. This engine has only 138 hours usage. Any ideas?
Listen for the full throttle pop sound on this video at
. The video starts with the engine at low idle, then moves to mid throttle and finally full throttle. That's when you can hear the "pop" toward the end of the video.
Thanks.
Robert
