Bugs down at full throttle
 

this go kart it has been sitting for about a year and now every time i punch the gas it bugs down, has a severe lack of power and it dies. i have removed and clean the carb, adjusted it and put new fuel in it. i dont know what to do any more, any suggestions?

welcome to the group-look for leak around intake-if you have to reclean carb use a breadtie thru jets after cleaning hold up to light and make sure you can see thru them

thanks for your help, there was no leaks arround the intake i used compressed air to blow the jets ans still does the same thing, somebody told me to check the timing on it, do you know where i can find a repair manual for this engine?

Yeah, I was going to say it sounds like a dirty or gunkey carb. It could also be that your carb is not jetted properly.

look in the manual section

For?
