Examination
Check condition: Engine cooled to at least room temperature.
1. Unscrew the air filter, see chapter Power system, carburetor, fuel injection system, Chapter Removal and installation of the air filter.
2. Ask an assistant to fully depress the gas pedal. Starter flap -arrow- must close to a small gap.
3. If the start flap does not close, check the ease of movement of the start flap shaft. If the start damper shaft runs smoothly and the damper still does not open, the start damper diaphragm should be checked (performed in the workshop).
4. Start the engine and let it idle.
5. Check if the case of the cold start automation is heating up. At the same time, the start flap in the intake pipe must open slowly.
6. If the case does not heat up, the automatic cold start should be replaced. If the body heats up and the damper does not close or closes partially, the start damper diaphragm should be checked (performed in the workshop).
7. Install the air filter.
Removing
1. Unscrew the air filter, see chapter Power system, carburetor, fuel injection system, Chapter Removal and installation of the air filter.
2. Disconnect the automatic cold start plug.
3. Unscrew 3 bolts and remove the mounting plate, bimetallic spring housing and gasket.
Installation
1. Install a new body gasket.
2. Install the housing of the starting automation so that the tongue of the bimetallic spring enters the lever of the starting damper.
3. Install the mounting plate and tighten the 3 bolts by hand.
4. Align the middle line of the scale on the carburetor body with the mark on the starting automation body. Tighten the mounting bolts.
5. Connect the starter automatic plug.
6. Install the air filter.
