Whew! Kinda threw me off there for a minute. I didn't now that the
1895 Chevy had a Q-Jet LOL. One problem with the older Q-Jets was the plugs in the secondary wells. They would leak after the carb heated up and fuel would leak down into the manifold through a weep hole in the base. This problem usually caused it to flood after it sat for a short period of time. The fix for this was to drill out the plugs and replace them with O-ringed plugs - OR - install a rubber plug in the void that prevented the wells from leaking.But, you said that it was leaking around the choke so this may not be your problem. Since you have replaced the needle and seat, did you re-check the float level? As I remembe it, the only passageways around the choke carried vacuum and heated air.
