" Hi
The availability of Champion spark plugs in Australia is limited. Is there an NKG replacement equivalant to a Champion QL78YC.
QL78YC according to Champion is Resistor-CDI, 14mm, 78 on the heat range?, standard projected core nose, copper plus design. NGK cross referance charts don't offer an alternative.
Is there any ony who can help?
Regards Guy Manson "

" I have an 89 88HP Evinrude, Lost power water bubbling out between the block and port side head.
I removed the head and found head gasket blown. The head is ruined because of a large wash out in the surface. The deck of the block has a small washout, but the cylinder liner still looks OK.
Is it possible to use something like JB WEld and smooth the deck succesfully, and replace the head?
Also do you have a head and gasket for sale and how much? Thanks for your help. "
