Saw would not stay running

Pliers, Screw drivers, Wrench set
I replaced air and fuel filters and new spark plug. Once I completed repair saw would start but acted like it would run out of fuel. I let sit for 24 hours and then tried it and it has been running good ever since. I believe the new fuel filter takes time to become fully operational.

Chain saw was running poorly. Short burst then stalled.

Replaced air filter, fuel filter and spark plug. Had a flange nut that was missing so I replaced that as well. After this tune up the chain saw worked extremely well, pretty much like new. Took all of 10 minutes.

Figured out that the tool that you get to remove paint can tops is perfect for fishing out the fuel filter.
