If you took the choke housing off, you will have to readjust it and may have misaligned the internal spring. Pretty easy to miss the slot in the internal arm w/ the spring end.
A quick way to check is to take off the air cleaner when it's dead cold...blip the throttle & the choke flap should close almost fully. If it doesn't, then loosen the screws & turn the housing til it just closes fully. It turns both ways, one generates more/one less spring pressure. If your's doesn't, you missed the spring. Pully the cover off & realign the spring correctly between the tangs on the internal rod. Then reassemble & adjust as above. Start & warm up the engine.....the choke plate should now rotate into the open position if the wire is properly connected.
Hope this helps.
