OS Carb Dimensions?

[GilBeQuick]

Where can I find the dimensions of OS carbs? I've been searching everywhere and still no luck.

What I really need to know is if the OS #20E carb has the same dimensions as the OS #21b carb? I know the RG's were discontinued and the RZ's replaced them, I wonder if the carb is just renamed the #21b. Anyone know? But if anyone knows of a page of the carb dimensions I can look it up. Thanks!

The RG discontinued??? Or are you just talking about a carb?

You're the man, thanks!

Olds, as far as I know, just the #20e carb.
