be sure your kill switch is set to run positon and the wires from it arent grounding theirself out . Make sure your spark plug is
grnded to metal when you check for spark.(ground to head away from the spark plug hole
You may have a bad ignition module if you still have no spark or the flywheel keyway has sheared for some reason throwing it out of timing.(removal of flywheel is required to see if the keyways are aligned flywheel and crankshaft)
If your flywheel seems tight then you may be ok
not a high failure rate but it has happened.Gap your plug at .030 then.025 see if that makes a difference? keep going to a smaller gap to show you may have a weak module not able to jump a wider gap.
just a couple things to check hope this helps maybe
SOURCE: I have an echo mfg'd Echo GT2000 string trimmer
could be but lets try some other things first
On the carb. you have a primer bulb have you pushed that several times and is there gas in the bulb itself?
Are all of your fuel lines intact and not broken or brittle including the primer bulb?
Are you using fresh fuel mixture?
Be sure your stop and run switch is in the run position.
find your air filter and remove the filter itself
then you will be looking at the inlet side of the carb.opening and a orange choke shutter
Take a thimbles full of mixed fuel and pour directly into the carb opening with the choke off( turn trimmer on its side to do this)
now with everything (except for the filter) set to run try to start your trimmer 4 or 5 pulls
does it try to run? runs and shuts off? if so then you have carb. issues
which you can either replace or rebuild
sometimes if you do not want to tackle it yourself then it is less time consuming to replace it
but not cheaper.
hope this helps you some

the only thing left is the coil that is inside the cover right next to the flywheel with a gap of 10 thousand of a inch a business card will work but a new coil is almost thr price of a new trimmer unless you have a used one
Testimonial: "Thanks for the help. We did look at the coil. Got about 30 volts out of it when we pulled the starter. I hope that means it's OK."
SOURCE: Ref: Stihl FS46 string trimmer. Broken Flex shaft.
Remove orange sheild,remove single screw holding head in shaft then grab head with pliers and twist side to side until complete head is free.You should then be able to grab part of shaft.On power head loosen screws {about one turn each} that hold two white case halves near trigger,I think there are four,then there is a single torx screw on the bottom of lower case half in the middle that must be taken out to allow tube to be removed.Romove flexshaft from top.Check 4 plastic burnt to flexshaft,if there is you must replace tube liner as well,usally around bent part of tube the liner will go bad.
