getting any gas. what is wrong? as i give the four wheeler gas it makes a "bluh, bluh, bluh, bluh" kind of sound like its flooded. i know its not flooded though, ive cleaned the carburetor, the needle valve, and made sure that the floats are working right. the spark plug is in good condition. ive even drained the gas tank to make sure that nothing can be clogging the carburetor. also, i've installed a brand new in-line fuel filter. the only other thing that i think could be causing the problem would have to be a valve in the piston not closing properly. what could be the problem, and how could i go about fixing it. please give details. i really dont want to spend much money on it.
