It opens a metered port in the cylinder. Normal compression levels it will reset on its own at the first time the engine hits. Now with the filter being damaged it have inhaled grit. Anyways have look at the cylinder on the exhaust port side or did a compression test? They are the first thing I do on a non starter then if things look good then induce fuel mix into the cylinder to see it will hit.

BTW this animal is nothing but a modified chainsaw.
