Naturally the original plug on this 'Flying Horse' has fouled already can anyone recommend a good NGK or other substitute for the 'Great Master' 4118C that comes originally with these puppies??

Thanks in advance and keep the shiny side up and the rubber side down :)
 
There are a dozen threads regarding which plug to use. Instead of searching for them here, I am providing a link to a website that sells replacement plugs that are known to work well with our engines

PS: If you run 32:1 you shouldn't have an issue fouling unelss your air/fuel mixture is excessively rich. Being in CO, its hard to get a mixture setting that isn't rich at a single part of the entire throttle range.
