Carb fuel level By wheezy (Read 382 times)

[wheezy]

I took advice from a post on another site and installed a clear carb drain hose in order to guage my fuel level in the float bowl.  I have adjusted the float tang several times and verified it's at 19mm before the spring is compressed.  The carb is running super rich it appears, to the point where the mixture screw does nothing. When I checked the level in the drain hose, it's even with the fuel line, well above the jet passages.  From a side view, it appears to almost be in the venturi itself.

My question for the carb experts is this:  Should the jets be fully submerged like this?  I think not, but want some more opinions.  Thanks.
