HT23 not wanting to shut off

When I run my HT23, it heats up, but then when I want to shut it off it does not want to shut off, It makes a couple more revolutions until it does shut off. It helps a little when I let it idle for atleast a minute. What could this be? I fine tuned my carb and put my idle screw down, but it still does that. I set my idle for 1000 rpms, is that to low? Any suggestions would be great. My key ignition is original, could this cause it not to shut the 12 volts off immediately going to the coil when I shut off the key?

Now some may disagree with this but I will put it out there it's a old trick we used in the auto industry back in the 70's for carbon I have done this for years and never damaged a motor yet while running at operating RPM and your air cleaner lid off, take a bottle of water and drip it into the carb not enough to kill the motor but enough to slightly drop the RPM what you are doing is steam cleaning your combustion chamber and also check your timing and point gap if they are off you will get pre ignition.
