Why does my carburetor bog down when I accelerate?
The “Bog” simply means the engine is not receiving enough fuel when you go to wide open throttle. While there are other issues that may cause similar reactions within the carburetor, often the problem can be traced back to the accelerator pump system. Incorrect adjustment is the typical culprit.

The problem of having an engine “sputter” is typically caused by a fuel system issue.
