Chain saw won't start hot

[grcauto]

When cold....DO NOT START...Use your heat gun and warm the mag real good......Does it start?....No....There you go..

No....There you go..

Sherlock holmes theory. I like it.

But, but... the mag is probably inside the flywheel. By the time the OP gets the flywheel and its cover (recoil starter stuff) back on, the mag may already be cool again. I would rather try testing the spark itself.
