Sounds like your jetting is off. You are lean on the pilot if it idles faster on choke. You are way off on the main and possibly the needle clip but I can't determine whether you are rich or lean. If you turn off the fuel and it revs better just as it runs out of gas then I'd guess it is rich on the main. If there is no difference then I'd guess you are lean on the main. The clip position is determined after you get close and start "fine tuning".
