    that jet sounds about right so I would look for other reasons that would cause this.Is your airfilter clean? what does the plug look like?

    While putting it back together you adjusted the jets, and thats all u needed to do :P adjust to the jet, your getting to much gas if your fouling the plugs am i right ?
