I also have yet another problem, I have a Homelite trimmer, it will only run for a few seconds after it starts.
To get it to start, after pulling the starter cord, I have to hold it in the extended position and leave it there for the engine to start. Where most people poull and let the rope retract right away, I have to not let it retract for it to start. Then once it starts once Ipull on the throttle it stalls.
I just changed the spark plug &the carb looks clean.
Any ideas as to what this could be?
Thanks for helping a dummy like me.
