Chainsaw Repair

I worked on a Husky 240 today that I swear had a fuel problem.   But through a process of elimination and scratching my head a lot I decided to replace the coil.  Bingo the coil was the culprit.   The saw would start and run for about 15 seconds and shut off.  You could pull the rope right away and it would do the same thing.   Never seen a coil do that before.  I put on a new coil and it ran great afterwards
