I was just putting my 2300 back together after a little refresh, and when adjusting the float level, the gasket under the screw on top gave up. Didn’t really want to order just that, so I started checking and old metering block for a hole with the right diameter to fit the screw. Presto!! The one in the corner was perfect! A little trimming, Finished with the float adjustment. $0.00. And no leaks
