Cleaning a dusty carb.

Blow and go. Worst thing is you will have to take it apart.

Most likely the accelerator pump will be dried out and some of the gaskets will be dry

My dart sat with fuel in the carb for 4+ years.(gas in the tank too)

A squirt of starter fluid and it fired up and ran fine.

Weeks after getting it smogged I rebuilt the carb, not one screw was tight. Fingers removed almost every screw that secured two parts with a gasket between.
