Dissasembled Stihl FS 55 and trigger spring went SPROING...

SOURCE: how do i set the carburetor on a Stihl FS-55
Over the past 8 years, the FS55 has had at least 5 different carburetors, and they have at least 3 different systems with different adjustments. Many of them do not have much of an adjustment and will not cure running problems. If you are experiencing poor running conditions, I would suggest some basic checks first. The spark arrestor screen is a big culprit on this model.
Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark
2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check cylinder compression
Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

SOURCE: Stihl FS 55 will not start
After trying to start several times, remove the spark plug and see if it is "wet" If it is you are flooding it. Do not pull the rope more than 3 or 4 times with the choke closed, whether it "pops" or not open the choke half way after the 4th pull and make sure you have the throttle trigger squeezed to give it gas
