Remove Fuel Ratio Control
1. Disconnect line (1) from the fuel ratio control.2. Remove the wire seal from the bolts.3. Remove two bolts (2). Remove fuel ratio control (3) after it is moved down and out from the collar.Install Fuel Ratio Control
1. Put the fuel ratio control on the governor. 2. Be sure bolt (2) of the fuel ratio control is connected in the groove of collar (1).3. Install the two bolts that hold the fuel ratio control on the governor.4. Connect the line to the fuel ratio control.5. Install a wire seal on the bolts.Disassemble Fuel Ratio Control
start by:a) remove fuel ratio control 1. Remove the bolts and the housing (1).2. Remove wire seal (2) from the bolts. 3. Remove valve assembly (3).4. Remove seal (4) and O-ring seal from valve.5. Remove the retainer (5) and two springs (6). 6. Remove three bolts (9) and cover (10).7. Remove valve (7), diaphragm (8), retainer and spring. 8. Remove pin (12) from valve (7).9. Remove cover (11) from the valve.10. Remove the seal from the cover (11).Assemble Fuel Ratio Control
1. Put clean engine oil on lip of seal. Install the seal (1) in cover (2). Install seal so lip of seal is toward the inside of the cover. 2. Install the valve (3) into cover (2).3. Install the pin that holds cover on valve. 4. Install spring (7) and the retainer (6) in cover (8).5. Install diaphragm (5) on the valve assembly (4) and in the cover. 6. Install cover and three bolts (11) that hold covers together. Install wire seal on the bolts with tool group (A) after the fuel ratio control is installed and adjustments are made to it.7. Put clean engine oil on seal and ring seal. Install the seals (1) on valve.8. Install the two springs (13), retainer, and valve assembly (12).9.
