its a weber single barrel, the little part number tag on it says TYF7627S. under neath that on the same tag it says B 4 8 0. this is odd, since weber part numbers dont normally seem to be set up like this. it also says "made in usa" on it, which im pretty sure webers usually are not. its definitely a weber though its a got a big weber emblem stamped on it and it says weber right under that.
also, does anyone think i can pass jersey emmissions with a properly jetted solex addhe side draft? i have one w/ manifold, but i was gonna kinda wait and throw that on along with a cam/header/msd/etc...
my problem is that the stock carb probably has an internal leak, which causes it to run a touch rich, intermittently, under acceleration. this is causing me to fail emissions. its like just enough that if i lean it out my NOX is too high, but if i dont im too rich, just barely. it COULD be something else, but i doubt it, everything is pretty tip top. new cat, plugs, wires, timing, etc. i've checked it all like 20 times at this point to be sure.
if anyone knows how gnarly the gaskets are in there, id even be willing to try to make new ones from blank gasket paper so long as they dont have like super ridculously complex patterns and stuff. i just dont wanna pull it apart and be f**ked.my guess is that maybe some gas is getting through an o ring for the jet or somehting, nut im not sure quite how its set up. im pretty good with carbs, but i never messed with this one.
