When engine is cold, spring around base of choke shaft

holds choke closed for starting. When engine starts,

governor closes throttle from wide open to set governor

speed. As throttle closes, link between throttle and choke

operates choke to a slightly open position. After engine

warms up, bimetallic spring overcomes choke shaft

spring force and holds choke completely open.

Use these steps to check function of link design auto

choke.

1. Remove air cleaner cover and element.

2. Choke plate should be fully close when engine is

cold.

3. There should be light spring tension holding choke

closed.

4. There should not be any binding when choke shaft

assembly is rotated, which could cause choke to

remain partially open.

5. When engine is started, choke plate should be 1/3

open. Choke plate should start to open and be

completely open within 2 to 3 minutes at room

temperature.

6. Reinstall air cleaner element and secure cover.
