2003年4月14日 · By his explanation, you can see that the main weakness of an electric choke is normally the operator not understanding that the choke is sort of on a timer. If you do not crank the engine immediately after turning the key, you can run out of time and are trying to start an engine with the choke partially to full open.

2010年5月14日 · The electric choke works by applying voltage to the heating coil in the round cover. The coil moves as it heats up thus opening the choke. It needs a switched hot. Yes it will take power even after the car is hot. It needs to, to keep the heating coil hot and keep the choke open. When you remove power the coil will cool down and close the choke.

2013年6月4日 · The bimetallic coil in the choke reacts to ANY heat, not just heat from the electric element. This is no different than a hot air choke. If the engine is warm, or the air temp is high, the choke will be mostly open even with the key off. It also will …

2004年6月14日 · However, you can look upon it as a electric choke for operating purposes.<br /><br />The RED lever on the primer solenoid should be over top of the solenoid, pointing directly at the other end of the solenoid to be in the automatic mode.<br /><br />When you push the key in to operate the solenoid (choke), that allows fuel to flow through the ...

2014年3月31日 · Re: electric choke operation Assuming this is the same as in my carburated 3.0 L Mercruiser. The electric choke is separate from the accelerator pump. The electric choke is nothing more than a bimetal strip that will close the choke butterfly when the engine is cold.

2003年6月7日 · Re: How does choke work on Mercury? Its not a true choke, more of a pressure carb fuel injector set up. A small electricle solenoid opens the fuel pressure directly from the pressure side of the fuel system and allows direct flow …

2011年10月29日 · After the idle is up to 1600 rpm the engine is running smoothly and during cold start up there is no black smoke coming out the pipes or anything and choked does open up just fine as engine heats up and is hooked up to a correct 12 volt source and also during cranking the engine the first time the choke flap does open about 1/8 of an inch or so ...

2009年7月30日 · Re: Electric choke not working Check out your choke solenoid. First make sure your getting 12 volts at the solenoid when the choke is activated at the key. If no voltage or low voltage find out why. If good voltage then disconnect the solenoid and check it with an ohm meter to make sure there is no break in the windings inside the solenoid.

2016年2月2日 · the secondary choke pull off is vacuum controlled by the thermal vacuum switch in the air cleaner.. so when the air into the air cleaner reaches a specific temp.. usually around 105F.. the secondary choke pull off is yanked open.. this pulls the fast idle cam down and allows the throttle to close. a very few only have a secondary choke pull off.

2004年10月7日 · The heating element is attached to the choke housing by three rivets or screws. If these aren't tight and the housing free of corrosion, paint, etc. the ground can be intermittent or absent altogether. Another possible trouble spot comes from the popular modification of converting an integral hot air choke to an electric choke.
