What 'color' is the plug? Black & sooty means the mixture is 'rich' suggesting a problem with the carburetor or air filter. If it is severe enough it requires correction.
What spark plugs are you running? If they are DR9EA try going one range hotter with DR8EA. I had similar issues early in Hidalgo's life and since switching to the DR8EA have had no spark plug related issues.
