Starting device — removal and installation

Removing the automatic starter

Auto Trigger Installation Tags

The operation of the starting device is based on the control of the control valve by a bimetallic spring. On a cold engine, the bimetallic spring compresses and opens the valve, resulting in an enrichment of the mixture, which is necessary for the normal operation of the engine. When the engine warms up, the bimetallic spring is heated by the coolant, expands and closes the valve.

Withdrawal

1. Remove the earth wire from the battery and the air filter.

2. With a hot engine, relieve pressure in the engine cooling system, for which, being careful, unscrew the plug on the expansion tank.


3. Unscrew the 3 bolts securing the automatic starter cover and secure it to the engine with a wire.

4. Unscrew the 3 bolts securing the automatic starter to the carburetor.

Installation

1. Install the automatic starter on the carburetor and secure it with bolts.

2. Check and, if necessary, adjust the starting device.

3. Install the gasket and bimetal spring in the middle groove of the lever.

4. Install the starter cover without tightening the bolts.

5. By turning the cover, align the mark on the cover with the middle mark on the body. Alignment of the mark on the cap with mark 4 on the body results in a leaner mixture, and alignment with mark 3 results in an enrichment of the mixture (see fig. Auto Trigger Installation Tags).

6. Install the air filter and connect the ground wire to the battery.

7. If the engine runs unstable during warm-up until it stops, align the mark on the cover with mark 4 on the body.

8. If the starting device is delayed, align the mark on the cover with mark 3 on the body.

Basic adjustment

1. Unscrew the 3 bolts securing the automatic starter cover and remove the cover.



2. Turn the driving lever clockwise until the holes in the brass bushing and in the carburetor body are aligned.



3. Insert rod into holes (2) the corresponding diameter. Loosen the nut on the drive arm (3), turn the lever (1) clockwise until it stops and tighten the nut.
