Default Coolster 125 atv won't stay running more than one minute
My son's coolster 125 atv will start and run for approximately 1 minute and then seems like it's wanting fuel
And stalls??? I've cleaned the carb twice, any ideas?

Run until it stalls, immediately turn off the petcock or clamp fuel line, loosen drain on float bowl and see how much fuel comes out.

Sounds like a clogged float valve passage...make sure you spray carb cleaner in the fuel inlet and watch it shoot out of the bowl...then you know it's clear...

if none of those work, I would get a new plug if it still has original.

Does the machine have a shut off or fuel filter? They may be clogged or gummed up restricting the flow of fuel as well
