Hi everyone, just pulled my Rochester to send off to be rebuilt, one question...

What is this part?

Looks like a rubber riser block. The reason I ask is that it looks very worn and is split on one side at the mounting point. Is it critical that I find another one before I attempt to reinstall the carb?

Thanks in advance!
