Squirted some starter fluid in the air cleaner and still did not fire. Pulled plug wire and out and put a bolt into the rubber cap to wedge in the spark plug contacts and held near engine ground and pulled- no spark was seen. Accidentally found it would still give a shock, but no spark so it was a weak ignition. A bit of a pain to take
... Read more apart to access the ignition module since you must remove it from the backpack carrier, and take off the fuel tank. But the pull cord housing comes off with 4 screws. Replaced it and used a business card to gap between the ignition module and the magnets while tightening the new module. Re-assembled and it starts right up and runs well. Note that there was very little difference in the Ohmmeter reading on the bad and new module so you cannot trust that. Check for a hot spark. I replaced the plug anyway but that was not the cause.
