Determine The Starting System
Before startingthe engine, youmust determine thetype of starting systemthat is onyour
engine. Your engine will have one of the following types.
Electronic Fuel ManagementSystem: This features an Electronic Control Unit that
monitors engine and temperature conditions. It does not have a manual choke or a
primer.
Choke System: This features a choke to be used for starting in cooltemperatures.
Some models will have a separate choke control while others will have a
combination choke/throttle control. This type does not have a primer.
To start your engine, follow the instructions for your type of starting system.
Note: Some engines and equipment have remote controls. See the equipment manual
for location and operation of remote controls.
