This sort of ugliness is why I go on about checking the timing on BOTH cylinders especially with old magnetos.

If this 'friend' is Kent Shaun, then quite possibly! ;-)

Chazzy lad it was Shaun and he was riding on NGK plugs and one did still work i have been told that Nippon plugs are best but after this ? I have been using champion plugs in my A10 for years and have been ok. I have seen Bosch plugs about in A10's as well.

Is this likly to be anything to do with spark plugs? I should have thought this had about one chance in a 100 to be anything to do with spark plugs. - Unless the heat range selected was miles wrong.

In 95% of cases this would just be caused by uneven igniton timing. Especially on a twin with a mag.

Hi John as i said in the first post it was the igniton timing that was the problem but the plugs had kept going with all the heat.
