This old chestnut again.....
I'm in the UK and really struggling to find replacement spark plugs for the 7815. However in my search on the internet looking at charts listing equivalent plugs for the 2407 and the 2344 up pops the XML15Y and the XML12.
Now the XML12 seem to be easier to find over here in the UK than the others mentioned. These plugs are 14mm have a reach of 1/2" (12.5mm) and the overall length is 3 8/16th inches in length. I can't find a temperature range for them.
This is the most informative link I've come across

Have any of you come across these plugs, and are they suitable for the 715, any thoughts appreciated.
Simon.
