Rebuilt my Carter 2100S with a Kit from the carbking and in the kit it had a small ball which i thought was for the acc pump check ball. The ball i got with the kit is bigger than the one that came out. The big one fits but does not look like it would stop any fuel when it pumps. I would call Jon but he only works mon-wed. Any help would be appreciated.

One other question, Is there one spring or two springs (one inside the other) that put pressure on the fuel metering rod that sits on the top of the acc pump rod.
