I take the float bowl off and it will squirt when depressed, but locks up within a minute of running. I blew out the passage in the metering block, no problem. I couldn't seem to get air to pass through the passage on the main body of the carb, and I'm not sure what to do next.

Take out the big phillips screw and the squirter then turn it upside down to get the brass needle out and there is a gasket under the squirter live every 24 hour block of time like it's your last day on earth
