Question about Stihl Saws
SOURCE: stihl ts 400 wont start
If there is good fuel in the tank and the plug gets wet with fuel, and there is a good spark stating the obvious it should go, if not there could be a mechanical issue, piston scored, rings worn etc,

You seem to have covered most things so its now down to some diagnostic tests, compression test, you should be looking for 120psi at least, any thing under 100 and the rings are shot. A pressure vacuum test, this will tell you if you have an air leak either on the crank seals or a gasket, to do this you need to blank off both inlet and exhaust and use a pressure tester through the impulse tube ( this tube will go into the crankcase )
