Kawasaki engine surges at full throttle.

This happens on cold start about 25% of the time. When it does, if I pull the choke all the way out for a second and then push it all the way back in, it usually clears up, but not always. If I rev the engine up, it clears up and runs smooth at higher RPM (past 1/2 throttle). This also happens when the engine is hot (after 1 to 4 hours of mowing).Joined May 16, 2013. 551 Posts. #77 · Sep 29, 2016.
