Very old weedeater runs-- barely
At my rental landlord left a beat up old weedeater in basement. "Needie 500," manual for similar model 507 is online and copyright 1976.
Electric, it runs but at about 2 mph. I opened it up to see if any dirt or grass stuck but nothing big visible although everything is covered with grime.
Curious if there might be a simple repair or at this point just give up.
