the engine to warm up prior to carburetor adjustment.
This engine is designed and manufactured in order to comply with
EPA (Environmental Protection Agency) Phase 2 regulations.
The carburetor is factory set and should not require adjusting.
The carburetor will permit only limited adjustment of the "T"
screw (Fig. 29).

such case the engine will not run in compliance with
emissions regulations.
