My 02 426 starts first kick. It goes into a high idle until I push the choke in, then drops to a normal idle like it should. But sometimes after it's hot it will idle high when I come to a stop. I will adjust the idle and it brings it back to normal. Any ideas?

A hanging idle is usually because of lean idle mixture. Try the fuel screw out 1/4 to 1/2 turn more.

It is normal for the engine to idle faster when warm than when just off the choke, but the difference should be reasonably small.
