Alrighty then! Now we're getting somewhere!

Another question. About killing the engine to let it completely cool down, would it be OK to four stroke the engine to cool it off, and then after it is cool enough to be able to be held by the hand, run it WOT for another two minutes at the previous needle setting? Or, does it need to "completely" cool, by shutting off the engine? Seems that by four stroking it, I would still be letting it cool, but saving time instead of just sitting there dead, while cooling.
