I've posted this before but obviously NGK found it necessary to issue this guide to identifying fake NGK plugs:
Which reminds me ........
I bought a 1947 one owner Model 18 that hadn't run for 25 years. I recommissioned it and replaced the 'worn out' KLG FE80 plug with a nice new NGK. It was the devil of a job to start it. I changed it for a new Champion but still I knackered myself trying to start it. Lost for options and without touching anything else I put the worn out FE80 back in. It started easily and ran beautifully thereafter. Not at all scientific and I can't explain why it 'liked' the FE80 but it certainly did.

Just to complete the thread.
I tried the suggestions and did eventually solve the mystery. First was to stop the leak from the fiber washer between the jet holder and the carb. body (couldn't get a seal with washers so used O-ring). The needle was on the second from bottom notch, it had run perfectly for the last 10 years on that setting. I returned it to the middle notch. Finally fitted a Champion N5C and the miss was gone. Thanks again for the suggestions.
