Chainsaw Repair

With the air cover off move the control lever through its range of movement from stop to choke.

There is a leaf spring that rides across the top of the choke - stop mechanism.

The loose wire plugs into the left end of the mechanism whereas the leaf spring will make contact with the side of the connector when the lever is in the stop position. When in the stop position the side of the wire connector makes contact with the bottom of the leaf spring and shorts out the magneto electrically and killing the ignition.

It is not unusual for this wire to become disconnected when cleaning out the air cleaner chamber area.
