Dear Scott,
Thank you for your reply. The choke assembly that I have is broken at the sleeve with the wire intact. The spring is 34" from the handle. The knob is a brass hex 1" in diameter with a circle on its face and I am assuming that it says "choke". The photo indicates the choke assembly placement next to the turn on switch, which I believe matches the choke handle.
I hope that this will help.
Thank you,
Bernie
