it will idle all day long but as soon as i give it more than half throttle it will bog out and die and then sometimes it will run great have full throttle while its on jack stands then i take it of the jack stands and try to ride it it will idle but then when u give it more than half throttle it will bog had it a couple of days ago running good my son was ridind it and even kickin up the dirt but then it stalled i checked the float its good no holes and the needle looks good i read that the eclip should be 4 from the top i havent checked that yet and theres 3 hoses comein from the gas tank one is on top in front of the gas cap when i got it there was a yellow handled screw in the hose is that suppost be there then theres a hose all most at the bottom of the tank in front of it that had a yellow handle screw in it to does that go to the carb cause i took the yellow thing out and put it to the carbs other hole that had a hose with a screw ib it then theres the bottom hose on the gas tank which is on the carb

 

you mean theres a vent line off the carb or gas tank? check to make all of these are hooked up and not blocked or pinched. can you ride it and it runs good and takes off fine or no?
