My Carter BBD is leaking. I rebuilt it and it runs fine, but after I shut the engine it starts leaking around the throttle shaft. I have taken the thing off twice to readjust the float, each time taking it down a little lower. I've got it way down now, but it still keeps on leaking.
I read where the carter is known for wearing out around the throttle shaft. I'm guessing this is what has happened. I have rechecked the little balls, tightened everything down really tight, etc, but no good. So...

I think I'll have to replace it. I found one on this site: http://www.nationalcarburetors.com/cat- ... gecar.html
Anybody know anything about this company? I'm assuming these are refurbished carbs. What are your thoughts on those?

Or should I replace it with a different one, such as the more expensive Weber? Any other brands you would suggest?

Man, this sucks. I thought I was doing good with my first rebuild. I was so proud of myself. But now I feel like a failure.

Don't let it get you down, You did good, leaking throttle shafts are a hallmark of the BBD. In light of all the effort you put into the rebuild, would have a machine shop re-bush the throttle shaft, even a rebuild is not going to have this done.

If you insist on replacement, look into the Weber conversions at WWW.prolinefuel.com, not the cheapest, But have read great things about them on this sight. Personally not a holly fan, but they also have a two barrel which was also used on the super six...Good luck...Dave
