Hello, I have a problem with quad atv 110. I did a light repair I replaced the cylinder piston heads carburetor coil and clutch because the old one was already totally destroyed. and the problem is that the quad is 1 forward, 1 reverse and loose. I put everything in the pile and ignite normally only after throwing the gear forward automatically exits, that is, pride him off and drive but as if there was no clutch. the screw on the side cover can not be adjusted, what to do about it? I put everything together as it used to be. HELP
