Not sure that having a petrol strimmer qualifies me as a tool junkie (but I do have a few more fossil-fuel powered garden tools, so maybe I do qualify).
Anyway, the aforementioned strimmer is getting on for 20 years old and the spare parts pile is near enough fully depleted, so when the primer bulb on the carb spilt and the thing spluttered to an way-over-lean halt, I thought that was very possibly that.
However, on extracting the split bulb - and it certainly didn't owe me anything - and having a measure I resorted to Goo*le.
Imagine my surprise therefore, to find dozens of generic primer bulbs in my size. Bought a few - the postage was more than the bulbs.
Fitted one of said bulbs and hey ho, it works perfectly!
I'm fairly adept at finding long-lost parts for my classic Triumph motorcycles, but long lost parts for 20 yo Chinese made petrol strimmers is a whole new experience.
