Hi,
i have a exmark lazer with a kholer 2 cylinder engine, its been backfiring and loosing power. its not really backfiring as much as sputtering i guess or it does kinda make a pop sound as its running. any ideas what it could be? i repalced plugs, air filter and sprayed this Amsoil spray into the intake to clean the carb/engine. it kinda fied the problem for a week but now its back.

Could be water/trash in the carb....

Take the carb. off, Tear it down and clean all ports and passages with carb. & choke spray cleaner with the little straw. Check the float needle valve for a wear ring around the tip and replace it if so.

Some of these carbs. had a low speed adjustment on the top but no adjustment on the high speed where it sounds like your problem is.
