This season the Sears weed whacker (strimmer)
now fails to run. (It started OK when taken from
storage and ran OK for less than an hour's initial
use.) I changed the diaphragm which was indeed
stiff (3 years old) but now cannot start the motor.
Is there a web site with useful trouble-shooting
check lists?
