Subject: Another leaky carb ?

I have 30mm square slide and rebuilt them with the MG cycle kits. The
left one seeps a bit of fuel, enough to only discolor the carb body and
maybe form one drip. This happens while running only.

Anyone have problems with leakage via the idle adjust or mixture
(although I beleive that is only a airpath)?

All outward seals look snug and no drips.

Thanks
