atv fuel problems

[redneckengineering]

so that chinese atv is running well, except for one thing. the carburetor doesnt receive fuel as quickly as it needs it. i know that it is low enough that fuel is siphoning, and i know it has nothing to do with a dirty carb, cause i cleaned it out twice, and the gas cap isn’t blocked. i don’t know for sure, but i think it might be the in line fuel filter as an air bubble forms in the fuel line right after it which eventually goes into the carb and starves out the engine for fuel. however, at the same time, if I pull the fuel line off the carb, the fuel line seems to put out fuel just fine. is something blocked up? do i drill out a hole somewhere?

Fuel filters are cheap.. try that and see what happens....
Try maybe replacing a fuel line... that also might be an issue...The gas might have attacked it and caused it to swell from the inside(from the alcohol in the gas) .. restricting some flow...
