I changed out the plugs in my 78 115 horse evinrude and went with NGK's, engine didn't run as well with the NGK's as it did with the old wore out Champion plugs, which I kind of expected from reading another thread on the matter.
I looked in the owners manual and the manual calls for either a Champion L77J4 or an AC M40FFX, these plugs are no longer available from what I've found, so what would be a good replacement? I found that with the NGK's I had worse low end performance, it likes to die when running at low idle (ie) pulling into a doc for mooring, it actually ran better with the old champions in it, so I pulled out the NGK's and put the Champions back in it until I can find a suitable replacement.
any ideas?
I'm finding this forum an invaluable tool by the way, the knowledge here is unsurpassed, better then any book, although I've ordered the maintenance manuals for the engine as well, it just hasn't arrived yet.
