Here's what the piston assembly looks like, after being freed up with a little carb cleaner and a drop of teflon oil. A little more brushing with a brass gun brush, I'll give this another washdown and lube, and pop it together.
The function of this assy is to have the upward stem seen in the photo work with the heat activated metal coil in the choke housing. WHen that coil starts to tug away at the stem, the piston you see in this photo adds stability to the action and supposedly keeps things from binding, etc. In reality, that piston is facing upward so it can collect dust and pieces of rust. Since this is a very simple device, it may be wise to pop it open now and then and flush things out, drop a little sewing machine oil or teflon oil in there and keep things reliable.
Regards,
