You've obviously never seen a 4 point cold seized piston. For the reasons stated above, the piston and cylinder don't warm up at the same rate, it takes a little longer for the heat to get in the cylinder. Flooding the engine with lube also is little help, when you go from piston to wall clearance to near zero, to press fit. This is most noticeable in cold weather. Summer temps ah, not so much an issue. You can do the same thing in automotive as well, just mush less likely ad they use a different piston casting technique that holds to much tighter tolerances then our typical cast or forged pistons we see. Our saws being low performance end of the 2 stroke spectrum, don't have near the issues others engines do, if not warmed up properly. But it can and does happen. After it's warm go rev it as much as you want. Heck go rev it ad much as you want, whenever you want. It's your saw.
