I do wear a tight fitting race suit.  The first couple times I experienced it, I assumed that I was bumping the throttle cable.  I did take care to analyze it, and I’m definitely not.

I should also mention, when the engine does this, the kart in general starts running differently.  The engine will bog down in places that it wasn’t a lap ago, and be kind of erratic with the power delivery.

To me, it seams like the kart is running too rich, so maybe I should change the jetting to lean it out.  However, why does it run amazing during the opening laps of a stint most days?
