Carter RBS Jets

[Mr Comet]

I have 3 jets for carter RBS carbs, one has the number 120 on it. The others have no noticeable numbers on them but they are both the same size. Does any one know what the 120 stands for? Or the size of the jet? What's the next size larger? Any help would be appreciated.

Thanks

Denny

You could check with a numbered drill bit set if you have one.

Thanks Econoline I have done that and found the two unmarked ones are between 3/64" and 1/16". I was hoping to see if anyone knew what the "120" was. and possibly what the next size up was.
