if you move the throttle by hand at the carb ( where the throttle cable attaches ) the choke butterfly should close.

there are a bunch of linkages involved that may or may not be working as expected.

On the passenger side of the carb is the choke spring that is supposed to move the butterfly ( flapper ), but there can be a dozen reasons it doesn't.

The simplest is it's mis adjusted. There are 3 screws on the face that hold a black plastic piece in place. Rotating that adjusts the choke.

With the engine cold you rotate it till it just closes, then snug up the screws.

If your choke system is working it will open as the engine warms up.

Note that the choke will NOT open until you blip the throttle as the mechanism keeps it in place. If you grew up in the north with carberated cars you will remember them racing untill they warmed up and you kicked the throttle.

The gas filter is screwed into the front of the carb, theres a metal tube that snakes around the radiator hose and connects to the carb. The filter is inside there.

It's usually on too tight and it will leak gas when you open it. so have some paper towels ready. Use 2 wrenches, 1 to hold the filter and the second to loosen the gas line, then loosen the filter.

You have to bend the gas line a little to get it all apart.

The filter has a right and wrong way to go in, I always forget which is right, so check the archives!

Ok, so i'm right about what the choke is, and that the green thing is in a vacuum line

Now, how is the pedal going to the floor (once) supposed to close the choke? I can move things but I don't know what should move together, what
should move the lever that moves the choke flapper?

I'm not having luck looking at images online for what moves what plates.

And finally, there's supposed to be a tiny gas filter in the carb, looks like a small gold microphone.

how do i get to/change that?

thanks
kelly
