try setting your carb, you will see three holes at the side of the machine nr to the fuel cap. the one at the bottom screw it in as far as it will go then unscrew it 4 turns, the one above it do the same again but unscrew it one and a half turns, if this dont work its possible draging air in from somwere ie, crank seals, inpluse pipe, gaskets. it will need to be presure tested.

It is hard to cause damage to a unit and be in business long. =) If you don't believe the shop that it is in, then I would take it to another shop that is a Stihl dealer with a Gold Certified Technician. I would also like to say that I would blow the fuel tank completely dry and then check the fuel filter. The filter should be dried after it is taken off of the fuel line and it might have some dis coloration since the fuel is mixed with oil. A new fuel filter should not cost very much in either case. Re attach the fuel filter to the fuel line, and add fresh fuel mix. There could have been some water in the fuel tank that would not be removed when the unit was tipped over. Test run the saw and see when it stops running. Is the unit hot? Did it bog down and die? These are things that should be noted and told to anyone that is working on the unit. I hope this helps you.

Sounds bad, the only answer here is to pull the cylinder off and check the condition of the internals, if there is a lot of dust behind the filter and into the back of the carb the engine is going to be in need of rebuild.

It should be threaded to the crank. On the end of the clutch it is hex shaped. I always used a metric socket and impact to pop them off. I am pretty sure they are left hand thread and there should be marked with "off" and an arrow showing this.

This was very common, they say it was because the screws were too long and prutruding through the nut the thread then gets covered in concrete dust and when trying to unscrew locks in the thread. You will probably have to destroy the cover to get it off.
