How do they work?
I had always assumed that they work when pressed in and with the key turned.
I watched someone hold the Key in prior to then turning it over without the key held in. Does pressing the key in without turning it operate the choke?
Cheers

Pete, on my old suzuki 100 the choke would operate by just pushing the key in with the engine switched on (first key position)
Dont know how it used to work cos nothing in the engine used to move all that happened was a very feint click from somewhere inside it.

On the Mariner/Mercury choke on 2 stroke engines is opperated by turning the key to "ON" position and pushing in (and held in), electrical current is sent to the enrichener valve causing it to open. Fuel is then sent to all cylinders via T fittings on the intake manifold.
The enrichener can be manually opperated should it fail to opperate electronically.
hope this helps..

you should here the solinoid click when you push in on the engine run position without having to turn it over.

Ideal gents, many thanks.
I did wonder if the ignition push was just a message sent and then the actual mechanics of a port / valve opening was done when the engine was turned over.
I wonder how often they fail? good to know they can be operated manually still.
Cheers again
Pete
