Electric choke issues, big surprise

Not a Mopar but a lot of good info on this site, I have a Holley Street Demon carb on my 78 F150. This carburetor is absolutely perfect until now. Now the choke sticks closed and fast idle cam sticks on. The kicker is that jiggling the battery negative seems to fix it, for a while but this morning it's all over the place, every time put the clutch in it would swap from fast to normal idle.

the cam and plate both have free movement. I know electric chokes suck but this carb is like a year old.
