The screw should have a spring on it... Pretty sure its on the bottom of the carb...but i am not sure. Ill look for that carb when im at my shop later today. There is a drain screw on the bottom of the carb that will only leak fuel...

 

that is what happened when i turned it out i dont see anthing else that is an adjustment

 

I am a idiot....I forgot to look for the carb....I promise to remember tomorrow. [img]i/expressions/face-icon-small-smile.gif[/img]

 

I found the carb...the fuel screw is right next to the idle screw. Idle screw comes straight out of the carb.Fuel screw comes out at aprox a 30 Degree angle.

 

then where is the air /fuel mix screw located at. ithought that was it?

 

If your looking at the carb its the screw on the left thast comes out of the carb at approx a 30 degree angle.. Large one on the right is the idle, it comes out straight.. This is how my stock 125 carb is setup. I would asume they didnt change it but you never know.

 

If it isnt this way I would look for a screw going into the carb from the bottom. Not coming out of the side of the bottom, but literally screwing in from the bottom.

 

there are only 3 screws on the carb 2 on the left which i think are the air / fuel mix and the idle screw and one on the bowl on the right which is the drain

 

The fuel screw is the one to adjust to try and get rid of the cogh and die syndrome it has. Start by turning the fuel screw in till it bottoms out and then turn it out 2 turns. If it gets better turn it out another 1/2 turn. If it gets worse turn it in. The fuel screw will have a affect on the idle speed...but dont sweat that unless it dies..if so thru the idle screw up some more while you adjust the fuel screw.

 

that is what i have been doing and it still doesnt work i can cet the engine to idle nice and smooth but as soon as i put it in gear it sputters like it is either starving or getting too much gas. but only when it warms up.this my problem.
