Default What is the correct spark plug gap for 129?

Took out my plug being that I'm having some engine issues as referred to in another thread - the plug doesn't look all that bad, but not real good either. For one thing, it wasn't even tight - barely needed a socket to loosen it. The manual refers to K241-K341 engines as getting a gap of .035 for either battery or breakerless ignition. But the same engines with magneto call for .025. Which is the correct gap? I assume .025? The plug I have now is at least at .030.
