Comer 50cc

[Hanka]

We are new to kid karts. Bought a kart and engine that runs strong for 7-8 laps at the Liberty race track and then it seems to run out of fuel and engine dies in left hand corners. Restarts fine and goes a couple laps and then dies again.

Running 87 pump gas and 6 oz. per gallon Klotz race oil. Spark plug has a nice tan color.

Any ideas?

Thanks, Hank

Check the vent in your gas cap, sounds like your caps vent isn't allowing any (or enough) air in.

Yes. Took it off at the track and removed the rubber inserts and can see daylight At first, it ran 7-8 laps fine. Later in the session only 1-2 laps and it died.
Removed carb and disassembled and cleaned... didn’t see anything obvious. Any other ideas?

Thanks for the response. My first time on this forum.
