hi you have a problem with NGK plugs you mite need a hotter plug you can be running to rich or burning oil if i have a problem that i ring NGK and get their advice on what ones to use and they have not let me down yet i have used all makes of plugs in my workshops in my lifetime and NGK comes out tops with me and my racing team

I switched to NGK's many years ago, with no regrets. I used to run a service station in the U.S. the amount of dud Champion plugs was quiet significant. I attended many rallies both here and abroad, clocking up mileages approaching Mr Carters. I found that the electrodes on Champion plugs just plain wore out, no such problem with NGK

Evening all,

I’ve come across these two Lodge SINTOX C14 plugs, the mate who gave them to me said he took them out of a WW2 outboard motor. Still has some of its war time green paint.
Had a quick comparison next to the NGK B6HS that’s on my bike and they are the same length and size.
So I just had to try it and what do you know, it fired right away, seemed to work well with it but I turned it off straight away as I know it’s not correct, when I made a cross reference from the Lodge C14 to an NGK, the equivalent is NGK B5HS.

Would this plug be too hot/cold for the WNG??

The bit you have to be concerned about is the length and thickness of the insulator in the combustion chamber. If it's long and thin it is a HOT plug only used in some (older) two strokes. An OHV Ariel needs middle to cold depending on how you ride. (Revs and load). A too hot plug can cause detonation, loss of power and engine damage.. Nev

them plugs look like aircraft with 3 electrodes with high voltage ignition

Multiple electrode plus were common at the time. They are generally considered to be of no practical advantage, and difficult to adjust the gap(s) Nev

They are generally considered to be of no practical advantage...

They are however easier to clean since the central electrode/insulator unscrews from the body.

what i have found with multiple electrode plugs you can get a misfire and you get a weaker spark if you have not got a good mag or coils and Leeds and caps
