A friend told me how his father spent something like $700 on a 17cc Kawasaki trimmer in the early 80s despite being warned they were no good and it was better to spend more on a larger capacity engine model. Being Dutch -known for being tight with their money- he said no it will do. According to my mate, it was the most useless gutless thing ever and had to replace it with a better not long after. They got a Dolmar which was a good machine but the shaft failed a few years ago, leaving a perfectly good running engine!
A pity Makita had to acquire Dolmar.
