Newbie vin/carb question

I am currently working on a 65 cj5(I'm pretty sure that's the year at It has the Buick 225 odd fire in it that is going to be checked out/refreshed. The vin plate that is on it shows 8305 s 219923 and I can't find what the 7th number means. The engine code list I found has a 4 as the lowest number so I dont know what the 1 means. Also what would be a good carb to run on that motor? The stock one has been rebuilt but when it was running you had to constantly pump the gas and keep the RPM's up in order to keep it running then it would eventually stall. Thanks ahead of time.

And the jeep in its current state

ECJ's don't have an engine code. 8305 tells us it is a CJ5, the last 6 numbers are the serial number.
As far as the carb, the stock Rochester 2G series is one of the best out there. I would check to insure the idle mixture and curb idle are adjusted before you chuck it. If you're looking to go bigger, you will need a manifold to do it properly. Summit still sells them new, and used ones pop up from time to time. A small 4BBl will really wake the engine up. Stay with a dual plane for the best offroad results.

Oh ok thanks for the info. I will have the adjustments checked after the shop replaces all of the bearings and stuff. I want to keep it as original as possible.
