fuel cap on 84 atc110

[spencersct]

The cap has on "on" "off" selector on it. I am not sure what it is supposed to do, but I know the fuel system will vapor lock to the point that I can't even get the cap of the tank. Does this selector need to be in the on or off position? Is it a vent of some sort? Any info would be helpful.

It is a vent, should be "on" when running the engine.

That's what I thought. I will try and test it. I don't think it is working.
