The Pulldown device is used in the carburetor so that when the air damper is closed (cold start system works) when giving gas, slightly open the air damper. Opening is done in two stages. Opening is done by vacuum, which is created in a separate container. If the Pulldown device fails, the engine is fed a rich mixture. In this case, malfunctions occur during the heating process.
Remove air filter.
Start the engine and let it run at idle speed.
if the choke can be easily moved up to a gap size of about 3.0-3.5 mm and then there is a noticeable resistance, the pulldown device is working properly.
If the air damper closes completely without resistance, either the diaphragm is torn or the vacuum system is leaking. Have the Pulldown device checked for leaks.
Install the air filter.
