I have stripped all the hoses, valves and solenoids from my carb, leaving only the bits what matters.
I don\'t know what to do with the "richer solenoid"
(http://i3.photobucket.com/albums/y96/matramurena/RIMG9183-960.jpg)
As i understand it\'s job is to prevent big bangs in the exhaust when coasting. The name "richer solenoid" means it makes the mixture richer during coasting?
When is 12 volt applied to the solenoid? Under coasting or when not coasting? In my application, should i connect a permanent 12 volt or not?
When i unscrew the solenoid, i expect a plunger, but there isn\'t. This is also the case on an other carb i have laying around. In the haynes manual there is a plunger showing in the solenoid. Should there be a plunger?
Hope this is some help,

All from memory here, last time I wanted to check this, I rigged up a little bulb, connected to the solenoid input lead and to earth. I popped the bulb up through the bonnet in front of the driver and went for a run at night.
I\'m fairly sure that the bulb lit up as I gear changed, so that every time I eased off the accelerator in between changes, it lit. That ties in with what you are saying about riching the mix for coasting. Applying a constant 12V will surely not be correct? Having no input might also be a problem? I don\'t know which is worse.
There is definitely a plunger on a spring in the solenoid - like a needle valve type of thing.....just looked in my spares box and it is so.
As said, the above light bulb results are from memory....I think that\'s the way it was.

That is opposite to that document above. But it makes more sense to me. As the name is richer solenoid, it suggest that when powered, makes it richer. Also the way i see the construction, when powered the coil retracts the plunger and opens an additional feed.
The thing what confuses me is that in my carb and spare carb there is no plunger in the solenoid. And to make it more confusing, when idling when i apply 12v to the solenoid, the idle gets rough. So even there is no plunger in, it is doing something.
I wish I could remember if that\'s the way it worked when I drove along. I remember being blinded on dark country lanes when the little light came on. Didn\'t I give you that warning? Sorry......:eek:
