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?

I use Marvel oil, Lucas top end oil and startron in all my tractors fuel. I mix it into my 5 gallon gas cans. Running it like this for year now and so far so good. I think that running a small amount in the gas all the time helps keep things clean as well as adding a little extra lubrication whereas gas today does not contain the lead that was needed for the valves.
