I have an echo mfg'd Echo GT2000 string trimmer with bent shaft. Gas not getting to spark plug. Could it be a bad Carb?

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

If your trimmer that has a bent shaft it is totaly shot. even if you bend it back it still will be shot. That once happened to me a car ran over my weedwacker and i bent it back but it still didn't run.
