Removing, installing, adjusting and checking the heating coil

Removing

Disconnect wire "masses" from the battery.

Disconnect the electrical wire from the automatic start unit.

Unscrew 3 bolts on the block cover, remove the cover together with the insert.

Installation

Install insert. Make sure that the groove is facing upwards and that the insert is correctly installed.

Install cover with spring and heating coil. The spring must be connected to the driving arm.

Install the cover of the automatic start unit so that the mark on the cover coincides with the middle mark on the carburetor body. Fasten the cover.

Connect the wire to the automatic start unit and the wire "masses" to the battery.

Adjustment

By turning the cover of the automatic start unit, you can change the time for switching on the automation. Changing the factory setting is not recommended.

Remove the air filter, loosen the 3 bolts on the starter cover and turn the cover. At the same time, observe the air damper in the upper part of the carburetor. If the damper must remain closed, turn the block cover so that the air damper moves in the direction "zu" ("closed") (at most - 5 mm from the marking). In conclusion, check the operation of the automatic start: the air damper must be open after warming up (those. vertically).

If the automatic start should switch off earlier, turn its cover in the opposite direction (max 5 mm).

Examination

Remove the air filter from the carburetor.

Slowly press the accelerator pedal; air damper must be closed.

Turn on the ignition.

Lightly depress the accelerator pedal so that the stop screw presses against the stepped disc.

Depending on the ambient temperature, the air damper should open after about 5 minutes. Otherwise, check the integrity of the bimetallic spring or the reliability of the connection of the automatic start unit to the battery.
