I once found one of those 1980s McCulloch line trimmers with a single line bump feed. It started up fine but was so weak I just let it lie amongst my pile of other discarded dead trimmers I had and never used it before eventually throwing it out with the rest.
I know someone who's father chose the cheapest petrol trimmer be could find back in the 1980s. It was a 17cc Kawasaki bent shaft waste of $800. It was absolutely gutless he told me. They later got a Dolmar which was good until the shaft gave up the ghost.

They ended up with a good engine with nothing to power. Dead weight in other words lol!!

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
