Rochester 2 Jet help!

[Beachcomber]

I just purchaced a 1969 Chev C10 with a 307 and 3 in the tree.
It is stock, untouched.

I have since replaced the gas tank and the 2 jet with a autoline C9070 rebuilt one and it was bogging off idle like there was no accelerator pump but it was pumping.

I exchanged it for an other 2 jet and it has no bog but it leaks fuel when I shut the motor off, leaking out the shaft and boiling on the intake.
and it surges off idle cruise

I could try another 3rd carb but I am not too amused.

Has anyone dealt with this carb and can I use a adaptor plate to bolt on a 2100 motorcraft or a holley 350 2bbl.

I am Paying $107.0 a liter and leaking fuel is bad news, plus it's hard to start cause it's flooded.

Do I throw the dice on another C9070?
