Weber carb advice needed

[NDoshi@domain.elided]

I need a source of information on adjusting Weber carbs. My GTV has 42DCOE's 
that are running rich at idle. Performance is very good otherwise. If someone 
can let me know where the idle enrichment screw is, I can try a little gentle 
experimentation.

Thanks
