Is plug getting wet?

Is it getting spark?

Is the mix 6 months or newer?

What is the psi?

Have you pulled muffler and checked piston and rings?

Looks like a nice light weight trim saw.  http://www.jonsered.com/int/chainsaws/cs-2240-s/

So does the tool-less tensioner system work good and seem sturdy?

Well you said you pulled flywheel right?  You have flywheel back on right and in time?

Loosen coil. Put a business card between flywheel and coil. Turn flywheel till both magnets line up with coil. You should see coil move into flywheel. The tighten coil.
