Step-by-Step Guide
-
Step 1: Check the oil level on four-stroke motors.
Make sure there is fuel in the tank and the fuel tank vent is open and clear. -
Step 2: Squeeze the primer bulb on the fuel line repeatedly until it is firm.
, On some controls, this is a lever beside the throttle/shift control that is lifted up far as it will go.
On others, pushing a button located in the hub of the throttle lever allows you to advance the throttle without engaging forward gear. , All outboards built before 1980 have choke plates; most of those built after 1982 have the enrichment system.
The enricher opens a valve that drains fuel into the manifold to provide a rich mixture for cold starting; choke plates accomplish the same result by blocking the flow of air into the front of the carb venturi.
If you have choke plates: push the key in while turning it over to the start position.
Release the key when the motor starts.
You may have a separate "choke" button instead of a "push-to-choke" key switch.
If you have the enrichener: turn the key to the "run" position, push and hold it in for 5 or 8 seconds, then continue to hold it in while turning it to the "start" position.
Release the key when the motor starts. , If it starts to die out, punching the choke for just an instant will usually make it recover. -
Step 3: Move the throttle into the hi-idle position.
-
Step 4: Determine whether your motor has choke plates or an enrichment system.
-
Step 5: Pull the throttle back
-
Step 6: allowing just enough RPMs to keep the motor from dying until it warms up.
