ECB00460 CAUTION: Make sure that the air filter element is properly seated in the air filter case. G Never operate the engine with the air filter element removed. This will allow unfiltered air to enter the engine, causing rapid engine wear and possible engine damage. Additionally, operation without the air filter element will affect carburetor jetting with subsequent poor performance and possible engine overheating. G EBU23881 1.
