My year 2000 8hp Mercury starts right up on the first pull. But then, as it is idling, it begins to rev up on its own, then coughs/misses and continues to idle. Eventually, it will sputter out and die.
I thought it was definitely a carburetor/air leak/gas tank problem, but I've cleaned the carburetor thoroughly twice, tried a different gas tank and hose, and searched thoroughly for leaks. The spark is good on both cylinders.
Here is a video of the problem (listen with sound). Thanks in advance for any help!
**if you can't see the video, try to download it– worked for me**
