Yes Max, very true about the spark plugs. These days they are not even telling us where they are made! I recently tried to track down the source of Windsor plugs which are supposedly Made in the USA, (or so a few internet sellers would have us believe!). I am now fairly sure they are in fact made by the Windsor automotive parts company which is based in India. At least there does not appear to be any auto-electrical company in the
USA called Windsor, as far as I can see. Also there does not seem to be any point of origin as far as suppliers go, with most sales being advertized by a handful of vendors on Amazon and eBay. So my guess is, nope they are not made in USA folks. It is becoming like Ripleys' Believe it or Not, and more often it is "NOT"! I am pretty sure the last Champion CJ8 I bought had no country of manufacture on the packet.

It is amazing how many people these days still think many of the former Australian-made products are still Made in Australia. Someone recently said to me "I'm glad I always use Colgate toothpaste because at least we know it is made here!" I had to break the bad news. I said Colgate has not been made in Australia for ages. I gave her a loan of my magnifying glass and pointed to the spot on the label. She was horrified. I said "Well it hasn't killed you so far and you've been using it for about a decade now, so chances are it is still the same product." grin

AVB, thanks muchly for the advice, I will definitely give those kevlar belts a try! Not sure why I hadn't thought of that before.

Back to Bosch WS8E plugs. I found some more for sale in the United States which looked promising. Sent the fellow an email: "Hi, Do you have any additional photos of the plugs and the original box? Are these "Made in Germany" or made somewhere else by Bosch?" Once again I never received a reply. I have found a few used ones that were made in Germany. Looks like I will just have to be satisfied with whatever fits and works. Most Chinese L6 plugs seem to work okay in old Briggs engines.
