That is not necessary on a 2stroke. You are either running lean (more air than fuel) or you have a old 2stroke with a bad combustion chamber design.

detonation or pinging does not cause that amount of excessive heat, but running to lean does cause detonation and extreme heat. Enough heat to melt aluminium.

here is a good read on the subject
