This was an adjustment problem, the electric choke has a fast idle cam as part of its assembly. It has an adjustable screw, when the weather is cold and choke closes the cam which is on the same shaft as what closes the choke also open the throttle plates to speed up the idle speed. The speed is controlled with a screw adjustment between the throttle shaft and the choke's fast idle cam.

I'd recommend putting the electric choke back and trashing the manual. Most people eventually forget the choke is on and leave it there running a lot of fuel through the engine which washes the upper cylinder lube away resulting in friction damage to the rings and upper cylinder wall, bring the next major rebuild closer.
