There is no way that thing is fat....plugs are way too clean! If it was me I would add jet....timing looks close to me....maybe...MAYBE add a degree AFTER getting jetting correct....not sure why no one has told you that but DEFINITELY not fat.....at least not up top....could be rich at idle...or getting some oil...I would be afraid to lean it out! JMHO Are you using a wide band?
