"I was able to get a hold of the exact sparkplugs for my old 65hp rude that the original owner's manual suggested. UL-77V....this plug is listed as a racing application on Champion's website. I asked for some advice here on the discussion forum and people told me to use L77JC-4 with a .030 gap setting. I found the Champion website and put my motor information in and it did list the L77JC-4 plug as the applicable plug that I needed. However, after purchasing 3 of these plugs, gapped at .030, it ran O.K. Then I purchased 3 UL77V's....UNREAL!!! When I switched over to the original UL77V plugs it fired up with no hesitation and seemed to breathe much better. I recommend you find your original OWNER'S MANUAL and go with the recommended plug. Not that the other plugs did any damage to my motor....but I feel that there is a reason they were listed in my owner's manual. The difference in the plugs is that there is no gap setting on the racing plugs!! here is a link
