My Subject line wasn't very accurate...the choke knob isn't getting stuck, per se...my issue is that after I use the choke, then push in the knob, it doesn't (at the carburetor) push the choke back to the original position, making it rev. So I have to open the hood and manually move it back to it's original position. I've tinkered with it over and over at the connection point where the choke cable attaches to the carburetor (not sure about the terminology), but I can't get that cable to return the choke to the original position? Any suggestions? Thanks.
