Stefano Posted September 20, 2011 Share Posted September 20, 2011 G3L spark plugs were 14mm with a 1/2" reach. Original fitment would have been either KLG F70, Champion L10 or Lodge H14 Accepted substitutes could be: Champion L82C or L86C NGK B6HS or B5HS Bosch W7AC or W8AC The first plugs listed are colder than the second, and if your engine has a tendency to oil up then you could go with the hotter plug. If, however, you've removed the compression plate I'd stick with the colder plug regardless. A cold plug at worst will stop functioning, a hot plug can melt a piston If in doubt you can always do a plug chop to see how things are going.

DaveP Posted September 20, 2011 Author Share Posted September 20, 2011 Thanks for the info Stef, need to give the old girl a bit of a tune up and couldnt seem to find a reference to a modern spark plug. The motor actually starts very well but does have an odd little misfire when warm, hope a new plug and some fine adjustments will sort it out. :tup::Thanks DaveP Quote Link to comment Share on other sites More sharing options...
