    As you guys alredy know I had alot issues with my carb
    but I have here up and running for now! rotfl


    But the top end is not there I thinik since the carb is further away from the engine I neet to move the needle clip!

    I think I need to move it down a notch

    i think I need to change my fuel mixture to 1/24 parts

    I have too much oil I have about 300 miles on the bike now , and I live 118 ft feet above sea level.


    I do consider this carb setup as a temporaty fix as I have said in my other posts. :D

    I had to do the same kind of change to my carb, let me know how the changes work for you. I have about 75-100 miles on mine and it will run 20 mph or so now. I run a 28:1 oil mix and have the e-clip on the second notch from the top.

    Run it for awhile and a) see if it gets better as it breaks in (it will) and b) remove your plug and take a look see...does it look rich?

    IMHO changing the needle clip doesn't change the WOT running too much. AND people think their engines are running lean and maybe they are actually running rich.......

    I left off that the jet size controls the WOT fuel, not the needle...

    You can make them a tad richer by tapering the needle more sharply to get a fatter mid to WOT.

    I wonder how many people cut their 2 stroke teeth on Cox model engines....running those as a kid make tuning two stroke easy for me now as far as two stroke/four stroke/rich/lean goes.

    2 stroke...nothin yet. I cut my general motorhead teeth on a 302ci V8 Mustang though :)
