When do you pull out the choke on a car?
Adjust the amount of choke you pull out depending on the engine temperature. More fuel vapor is present in a hot engine, which requires less choke. Pull out the choke knob more for a cold engine start, or on a cold day. More fuel droplets and less fuel vapor are present in a carburetor on a cold day, so you require more choke.
What does choke control do on an engine?
The manual choke control system allows the small engine equipment operator to temporarily adjust the fuel to air mixture and makes starting an engine that has not been used for a considerable length of time easier. The expression; “choke the engine ” refers to placing the carburetor manual choke control into the engaged (starting) position.
When to move choke control to normal position?
*Cable-style choke control pull-knobs should be pulled out to activate the choke . As the engine operating temperature warms and normal fuel flow is established, the choke control will need to be SLOWLY moved back to the normal operating position, as not to cause the engine to stall from too much fuel.
Where do you put the choke control cable?
Place the choke control cable under the intake manifold from the front of engine (front pull choke). Insert the cable bowden wire into the choke control (front or reverse pull). Then place choke cable under the cable clamp.
How do you install choke control on a car?
2. Place the choke control cable under the intake manifold from the front of engine (front pull choke). Insert the cable bowden wire into the choke control (front or reverse pull). Then place choke cable under the cable clamp. 3. Position the choke control so it bottoms, then pull it back approximately 1/16″ (1.5 mm).
When to move choke control back to normal?
As the engine operating temperature warms and normal fuel flow is established, the choke control will need to be SLOWLY moved back to the normal operating position, as not to cause the engine to stall from too much fuel. The speed at which this control is moved back into the normal operating position will vary.
When to take choke off of car engine?
If it is suspected that the engine may still be warm enough to re-start after a short break, such as less than 15 minutes or so, try re-starting it with the choke off. A warm engine should start easily with the choke off.
Which is the first step in choke adjustment?
Diagnostics The first step in any choke adjustment procedure is to locate the proper specifications for your car from a factory shop manual. Most earlier pull-off specifications were keyed to a drill bit size, while later Rochester carburetors used a more exact choke angle gauge, as seen in this primer.
