Er, Bob, I might have spoken too soon -- I just assumed (ass out of me, etc.) that Kelly was referring to the fact that it's generally a bad idea to wring the little engine's neck until it's warmed up. I didn't know that running the engine cold at WOT (maybe?) is part of the jetting procedure.
I have no expertise in this, so I'm going to back out of this conversation and let somebody else clarify. Sorry!
