Rapid plug failure in Chummy

I was far from impressed with two new differently numbered Champion spark plugs I bought from a reputable supplier for my two-stroke hedge trimmer and petrol lawnmower. On opening the boxes both had serious manufacturing defects so I complained to the supplier and chose not to use them - there was no country of origin on the boxes, but I suspect China. I then bought a couple of NGK from another reputable supplier and the difference in manufacturing quality straight out of the box was very noticeable. Be aware there's lots of fake NGK and possibly fake other brands on the w.w.web, so buy from a reputable supplier. The NGK plugs I bought have 'Made in Japan' or 'NGK Nagoya Japan' printed on the box.

Champion L86C - these plugs superseded the previous Champion L10 many years ago. The NGK equivalent to L86C is NGK B5HS 4210 but as I mention above, buy from a reputable retailer.

Jeff.

Here's the Champion box and plug that I received from the Green Spark Plug Company last Wednesday. They were out of stock of NGKs - I think they said that delivery was due early September - but suggested that this would be a close match. If Green Spark Plug Co. (who must order lots of plugs) has to wait months for delivery one must assume that they are the real deal. I hope this helps.
