i checked the two things recommended by you guys here:

- jet wells are good
- O rings were in place and looked good, too

any other ideas what could be causing the fuel leaking and dripping from the primary throttle shaft?

btw. anyone heard anything from Demonsizzler lately? it has been a while that he posted here and i couldnt get hold of him by phone or mail yet ...

Is there any play in the throttle shaft? Worn bushings can drip fuel as well if they are REALLY bad, but then Im sure you would have a big enough vacuum leak you probably would have been aware of that.

The main problem with those carbs is the platic center section. They tend to warp. I've ran one across a fine piece of sand paper to get rid of a a small warping problem. As far as fuel leaking from the throttle shaft. Sorry
