Murray carburetors are built to tight tolerances—aftermarket replacements often miss critical gasket seals or float height specs.

A clogged carburetor is the most common culprit, especially after winter storage. Stale fuel leaves varnish coating inside the jets and needle seat, blocking fuel flow.
