idle mix screws, base setting?

Sounds like the metering rods may be outta adjustment. Find the small slotted screw right in the center of the metering rod piston. take your hand and very slightly push the piston and metering rods down until they bottom slightly and hold them in place. Then, whil;e still holding the piston slightly bottomed out, turn the screw counter clockwise until the metering rod piston stops dropping down. Then, while still holding the piston down, start to turn the screw clockwise. You want to turn the screw ONE full turn clockwise from the point the piston FIRST started to come back up. That's your base adjustment. From there, you can fine tune it. counter clockwise is lean, clockwise is rich. I would not go any more than about 1/4 turn at the time while fine tuning.

well it seems to like a hair over 3 turns, idles 800 rpm, and holds a steady 9 on the vacuum gauge, I don't know the cam size, but I know it has a lot of over lap, now what can I do about the fumes? I'm talking burn your eyes and make you cry fumes, before I got the carb set, I couldn't get it to idle below 1100 rpm, but now the idle is fine, stays running in drive and starts right up, my timings set at 10 btdc, thanks.
