i had one of them off today, 40 DCOE, and it seems like there is a large amount of fuel seapage in the venturi area, can these guys leak? i thought there was only one possible gasket on them? or am i wrong? and where might i look for a rebuild kit?

steve..

I'm pretty sure they can leak. Mine were a mess to deal with. Just make sure that everything's tight. I know that on mine, I was missing a few of the auxillary venturi retaining screws. I think if there's too much pressure, gas can leak for anywhere.

Just a guess.

Webers will leak into the venturi if the fuel enrichment circuit is leaking. This would be the choke circuit, in other words. Apparently, the feed for the circuit is below the fuel bowl level so if the valve is not seated correctly fuel will weep into the venturi. It will also be drawn in at idle causing a rich setting that no amount of tuning will cure. Check this first....
