Weber Carb Help - Runs Too Rich

I have a stock Weber 32/36 on a 258 that continually runs rich. It shows rich on my air/fuel gauge and with a voltmeter (.8 volts). I am on the verge of stumbling with the air fuel mix - in other words, I have leaned it out as far as I can. Sooty tailpipe and black "puffs" on startup. Here are things I KNOW -

I have no vacuum leaks
performed top engine clean
Cleaned/resealed carb
Good choke
I am running between 3 - 3.5 psi on my fuel regulator
New plugs (burning clean)
TFI upgrade/Nutter bypass
No emissions/Cat converter
Timed at 13 [email protected]
Runs/performs great! (except for poor mileage and running rich)

What else should I look for? Do I need new or different jets? If so, which ones?

Re: Weber Carb Help - Runs Too Rich

get used to it. that's what webers do. they can be a good carb but it takes alot of work to get them good. they all come jetted rich out of the box. mine was horibly rich. i suggest getting the weber carb book, i think 4 wheel drive hardware sells it. if you order a jet kit for it i believe they come with many different sizes.
personally I got so sick of messing with mine i took it off and put my 390 holly back on. but then again i hate all carbs. fuel injection is next. i'd sell that weber pretty cheap if anyone wants it.
