Your engine has no idle adjustment needles for mixture, if it's bad enough you would have to remove the plugs on the outside of each carb and change the jets, they are air jets so you will have to decrease the size to richen the mix and increase the size to lean the engine. Also you can change the mix a little by trimming the engine, out is lean and in is rich

Thanks, I Appreciate The Help! Would You Have Any Way To Tell Me How To Set The Timming Right Then Because I Know That It Was Either Running Lean Or Rich Or The Timing Is Just A Hair Off, Because When I Let It Idle At 600 Rpm It Dies. But If I Set The Idle Up To About 1000 It Runs Great And Top Speeds At About 5000rpm At About 50 Mph.
