Sonofa......!! CARB HELP!!!

[cpnbnanamn]

So.. My truck's carb was starting hard and not running like it should.. And looking at the carb, it looked gummed up, so I decided to rebuild it. I tore it down, and dunked it in a carb cleaner, and am in the midst of rebuilding it, when I discover this... Hole. It's apparent SOMETHING was in there.. but I know for CERTAIN, I DIDN'T take anything out of it.. According to the exploded diagram I got with my carb kit, it's for the 'valve-idle vent (BV)' Yeah. I'm confused. I thought I had a 'B' carb?? Now, I'm not 100% sure WHICH carb I have!! The numbers that I found on the inside of the top-half of the carb are 7025523.. And I'm not sure if that matches to anything relevant!! (Edit: From what I'm reading, that's a casting number, and not relevant.)
HELP!!

Does anyone have one of these laying around that might have the parts I need in it? I am hoping I don't have to go buy a new carb....

There is a valve that goes in there that looks like a slotted screw head. It opens when the throttle closes. I may have one but I won't get back to the shop till sat.

I appreciate you looking.. I'm not looking forward to having to buy a new carb just for a couple of lousy pieces!!

I'll look sat. That is a Model B Rochester. They have many variations through the years. Not all have that vent valve.

Well, I don't have one. I think you can put a plug in the hole with a small hole in it & it would be OK. I will send you a private message.
