Hi guys. I have a Kohler Magnum M20 on a Cub 2082. I got this about 4 months ago. I broke down and cleaned the carburetor and reassembled to Kohlers specs. The motor starts up and runs great. After about 3 minutes or so i notice that the exhaust pipes that run from the heads to the muffler behin to smoke. It is not heavy but it is enough to concern me. I will try to post a video.

Forgot to mention that the noise in the background is my wife using the leaf blower and not the engine. The engine runs very well and strong.
