it's #23. #25 was salvageable as I didn't tear it up.
Is #23 super critical, or can I make my best guess on the internal opening and cut it out with an Xacto knife?
Also, I drilled out the pop-rivets on the electric choke assembly to separate it so I could remove it from the baseplate and soak the baseplate in my can of carb cleaner. Is the bi-metallic spring supposed to have pre-load on it when I reinstall the outer housing?
I know what the orientation of the two halves is to each other(took plenty of digital pics, sure makes it easier than sketching everything like I've done in the past), but I can;t recall if there was tension. I do not think there was, but am not sure.
Finally, what is the mode of operation of the bi-metallic strip coil?
Does it contract and pull the choke plate open or closed?
Thanks, you've been a great help to me over the last few days. I'm hoping rebuilding the carb will fix my non-running problem of a few days ago you were helping me with.
