Information:
1. Install Tool (A) as shown. 2. Install Tool (B) in the fuel pump housing as shown with the square end down. Use a small amount of hand force to push down on Tool (B) while the fuel control lever is moved forward to the "FUEL ON" position. Rack travel will stop in the center (zero) position. Hold a light forward force on the governor control lever to keep the fuel racks in the center (zero position). 3. Use Tool (A) to turn the engine in a counterclockwise direction (as seen from the flywheel end of the engine) until timing bolt (2) can be installed into the flywheel. The No. 1 piston must be at top center on the compression stroke. If
