i know there is an o'ring between the carb and the spacer, but is there supposed to be another o'ring between the spacer and the reed cage? seems like i have a groove for one, but its not there, and the parts breakdown's dont show it

 

no one knows? jack? anyone? lol

 

The reed cage has a rubber ring molded into it...

 

dam so if that rubber fell apart i gotta get a new one i guess, or pull the reed cage out and match up an o'ring for it, cuz there is a groove just like on the spacer, thanks jack, i appreciate the help

 

I've never seen one rot. I suppose if it was exposed to carb cleaners or the like long term it could happen.
I bet if you put a bead of silicone in place of the oring (and let that harden before install), it'd be OK.
If it's tight and not moving around, all's well right.
