I have a 3+ year old Weedeater Featherlite XT25 that will stall once
it is picked up and put into the "operating" position. That is, it
will sit on the ground and idle, rev, etc. with no problem, but within
30 to 90 seconds of picking it up to use it, it stalls, or, if it does
stay running, it will bog and stall out when I pull the trigger. I
have tried the following: removed air filter, removed fuel filter,
cleaned and rebuilt the apparently disposable carburetor, removed the
spark arrestor, checked for carbon in the cylinder, replaced the spark
plug, and replaced gas with fresh, proper 40:1 mix.
If anyone can lead me in another direction, I would appreciate it. I
told myself $20 was the max for repairs on this mostly disposable
item, and I'm up to $16 now.
