when I was about 7 I was cutting the lawns and when I came to shut the mower off the earthing bit was missing so got an old hacksaw blade and touched the spark plug,not sure how long I held on before I thought I'm getting a funny feeling here and let go , might explain a lotBriggs and stratton engine where you had to short the plug to stop would often give a heart stopping shock to the unaware
Bought some cut out switches from mole valley but the don't f@#king cut out! Leave 1kv coming down the fence line. Not inmpressed! Taking all of them back as they can not test before suppling replacements.
