Rochester 2 jet identification Q

I am rebuilding a rochester 2GV I can't tell what year it is. It came with a rebuild kit GP Sorensen 96-111D I have tried to cross reference the # but to no avail. Any help would be helpful

 

Oh man....you a Buckethead,too? Hoo hoo....anyway, grab your wire brush and give us the number off the side of the carb body...then we can tell ya what it is. There were so many of those little ******s made....thats the only way to really tell....

 

96 111 is for 2gs
covers almost all of them

 

If it doesn't have a number stamped in the p***enger side of the fuel bowl, it's pre-1968. The problem with the '67 and earlier 2 bbls. is that when someone threw the I.D. tag away, it made it just about impossible to identify it. Does it have the choke thermostat on the air horn? If so, it's '63 or earlier. If it uses a divorced choke (thermostat spring in the intake), but doesn't have an I.D. number stamped in it, it's '64-'67.

 

It has a # stamped in a circle on the side &031770 ( the& represents a number I cant read but I think it should be a 7)so 7031770

 

One more 2 jet question, there is a fuel line that comes out the bottom of the float bowl, is that an overflow or a fuel return or some kind of vent

 

NOT a fuel line
it was a vac*** line
plug it and use full manifold vac***

 

Thank you

 

Actually that vacuum port is connected to manifold vacuum. It goes straight down through the carb body ligning up with a hole in the carb base that opens up to the cavity below the throttle ****erflies....manifold vacuum. That is where GM hooked up the vacuum line for the vacuum advance but it is still full manifold vacuum. Yes GM distributors were designed for full manifold vacuum. Leave it unplugged and it won't run. You'll have a m***ive vacuum leak. Some of them were steel hard line and others use a rubber hose. It goes into the carb above the ****erflies but it connects to manifold vacuum below them.

 

The 2g series of rochesters all use the same basic rebuild kit. The next letter in the line up denotes the style of choke ***ociated with that particular carb. Some were operated by a bimetal spring whle others are either water or manafold heat control and then finally manual. Charlie Price at www.vintagespped.com sells rebuild kits for them and ***ociated replacement parts.
