650 speed demon issue

Has anyone ever experienced a bit of gas coming out of the full manifold port on the speed demon carb? not alot but enough that when i pull the vaccum cap of it's wet.

the floats seem ok maybe a tade low but defiantly not high

perhaps there is a bad gasket or o-ring in it allowing gas to seep between the mettering block(s)?

i have the same carb and when i got it the only problem i had at first was the fuel viewer leaked but only till it preasureized then it stopped leaking..id agree either bad gasket or o-ring..call the guys as demon and tell em bout it and see what they have to say....if you already havent taken care of the problem

Somethings wrong with it... Take off the fuel bowls and metering blocks and replace those horribly crappy red gaskets with the blue Holley non-stick ones. Problem solved, forever.
