What should you do if you put to many drops of smoke liquid into your HO engine and it stops smoking. It was working before.
Sounds like too many drops. No experience with these locos. I would just keep it running. Better than running dry. You must have instructions with the loco.

Run on full power (or just fast enough so that it doesn't fly off 18" radius curves, thereby launching your engine into the stratosphere), blow into the stack (popping any bubbles that could be prohibiting smoke flow). It'll happen eventually, just be patient. If, after a good 30 minutes it doesn't start smoking, just leave it on a table to let the fluid evaporate out.
Good luck ;D
