CARBURETOR ADJUSTMENT

WARNING: If any adjustments (e.g. carburetor) are
made to the engine while the engine is running,
keep clear of all moving parts. Be careful of heated
surfaces and muffler.
The carburetor has been pre-set at the factory and should not require
adjustment. If your engine does not operate properly due to suspected
carburetor problems, take your Yard Vacuum to a Sears Parts & Repair
Center for repair and adjustment.

by tampering with the engine's governor linkage.
Doing so could result in serious personal injury and
damage to the engine. The engine RPM has been set
