Re: What are these things?
It is spring loaded closed.
It needs 12 volts to heat up the bi-metal spring and then the spring
unwinds and opens the choke up.
I would be thinking the spring has broken. There are three screws or
three rivets holding the black cover on the choke. The spring is inside
there.
It is a bugger to get off without first removing the carb. 'Really'
short screwdrivers work or I used a screwdriver bit in a vise grip
sticking out to the side so I have a right angle screwdriver.
If the choke cover isn't on right, the choke can be forced open at rest
by turning the cover....

Re: What are these things?
"I would be thinking the spring has broken."
That is what I will check since it seems to be stuck open. Thanks.

Re: What are these things?
It is not in that drawing.
If you look on the valve cover side of the carb, you will see a black
round cap with an electric plug on it. The spring is inside of and part
of this cap.
I tossed mine in the garbage and got a manual choke kit.
Here in Canada, the stock 'timer' choke is crap in the winter. It opens
according to how long it has had power, not on how cold the engine
actually is...

Re: What are these things?
Our local auto parts store, Canadian Tire carries them for about $25.00.
They come with a replacement black cap with a lever inside instead of
the coil spring and are pretty easy to put on.
It also gives me a 'hand throttle' for keeping the revs up when I am
winching. I can give it gas until I get to 1500 or 1800 rpm, pull out
the choke, let off the gas and push the choke back in. The gas stays on
the fast idle cam at whatever revs I had it until I blip the throttle,
then it drops back to normal.
Same for driving away in cold weather, I can just leave it in 1200 rpm
or so with some choke until the temp gauge starts to move. Sometimes
that is 10 miles later.
