Troubleshooting - Gravely Pro-Stance 36 CARB Owner's/Operator's Manual

Fuel System
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
IMPORTANT: NEVER store the engine with
fuel in the fuel tank inside of a building with
potential sources of ignition.

crank.
