Trying them all
When you say the saw doesn't pull smoothly, have you tried pulling it over with the spark plug out? It should pull over easily in that situation.
Some things to check:
Make sure the flywheel isn't contacting the coil. There should be some air gap in there, many guys use a business card to set that space. (need .008 to .013" or so gap)
When you say you have no spark, did you try it with the spark plug out of the cylinder with the plug hooked to the wire and the base of the plug grounded?
Have you tried a different spark plug?
Check for spark "inside" in dim light, sometimes if you are outdoors, it is so bright you can't see the spark well.
Check the wires in your switch, (follow them) to make sure they aren't shorted somewhere turning the saw "off" even though the switch is in the "on" position
When you say, "no spark" do you mean the saw won't fire or you checked the above and the ignition system isn't working?
130 is on the low side, pull your muffler with the spark plug out and look in the exhaust port while slowly pulling the engine over to examine the condition of the piston and cylinder. It is possible the piston is scored (scraped up)
Report any additional findings.
