What causes an engine to score/blow up when using a dull chain?

[QUOTE="banditt007, post: 5121731, member: 96627"] A dull chain.... -reduces load on the saw (richer mixture) -"cuts" at higher rpm (richer mixture) -clogs up the air filter much faster (richer mixture) -creates fine dust (blocked cooling) A user of a dull chain, typically... -presses harder and reduces bar life. -presses harder and bogs the engine (leaner mixture/over heating) So I'm thinking what really causes the problem is the USER pushing way too hard to make it cut, which bogs the engine, which puts you into lean mixture territory, and also reduces the air flow across the engine. So would you agree this is the true cause of engine failure? Because on the surface, a dull chain seems like its easier on the engine, for the most part... [/QUOTE]
