I need help ! Here it is the thing runs like a new machine idling purz like a kat. But if u give it any gas to speak of bogs down sputters and pops back sumtimes ? I have changed the gas thinking i got sum bad gas, changed the plug , takin the carb off and cleaned bowl and blowed thru what air holes i could get too still same thing? Its getting gas u can see alot of gas in the carb when u give it the gas ! Man it is driving me crazy what throws me is how damn good it runs idiling ? Any help plz Thx Dave.  

take the airbox lid off see if it runs any better at all.
if so then it is too rich.
if it runs worse then it is too lean.

locate the air/fuel mixture screw
turning the screw to the left will increase the amount of fuel in the mix, turning it to the right will decrease the amount of fuel in the mix.

if removing the airbox lid has no effect at all then inspect the diaphram in the top of the carburetor for holes.

if no holes there then chances are it may have jumped a tooth off on the timing.  

Your park brake is on or you have a bad switch controlling that; There is a switch (retard ignition or something) at the brake lever and it is there so you do not tramp your machine and break something with the brakes on.


let me know if i am right. I always am...LOL!  

Yes mine did the same thing, it is the switch on the parking brake, even if it is out just a little bit or broken.
