Determine The Starting System
Before starting the engine, you must determine the type of starting system that is on your engine. Your engine will have one of the following types.
∙ReadyStart® System: This features a temperature controlled automatic choke. It does not have a manual choke or a primer.
∙Choke System: This features a choke to be used for starting in cool temperatures. 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.
