Ignition advance is electronically controlled. A twist grip at the steering handle is used to control throttle settings. Stroke: 5Hp Number of Cylinders Ignition Type Carburetor Make Mikuni Idle Speed in gear.. See Text 0. Piston Pin Diameter. Crankshaft Runout at Cylinder Head Screws Standard Screws Fuel:oil ratio should be I during break-in of a new or rebuilt engine. For normal service, fuel:oil ratio shou ld be 1 on models prior to and 1 for and later models.

Manufacturer recommends regular or unleaded automotive gasoline having an octane rating. Gasoline and oil shou ld be thoroughly mixed. The lower unit gears and bearings are lubricated by approximately mL 8. Reinstall vent and fill plugs securely using a new gasket , if necessary, to ensure a water tight seal.

Final carburetor adjustment should be performed with engine at normal operating temperature and running in forward gear. Adjust pilot air screw Mikuni Idle Speed in gear Wear Limit.. Wear Limit Piston-to-Cylinder Clearance: DT9.
