Place the voltmeter positive lead to the smaller wire terminal on the solenoid (usually purple or yellow), and the voltmeter negative lead to a ground source. Have your assistant turn the key to start the engine. The voltmeter should read 12.6 volts or more. Listen for the solenoid to click and the starter to spin.
Why does a 2 stroke run better with choke?
A clogged air filter restricts the amount of air that can go through to the engine. This can cause it to run lean enough to need the choke on to run. Keeping the filter clean is just one of several important maintenance items that should be regularly checked or serviced.
Why do 2 strokes need choke?
When a two stroke starts up, the choke cuts off a large portion of the air supply, causing more vacuum, so more fuel is burned at the start. On an auto-choke, this vacuum will open the manifold to let more air into the engine and they will also let more air into the engine the more heat that they produce.
