The plugs have been replaced but why would new plugs give more timing? I don't see that but I don't see a lot of things

Les is running 26.5*. 1.5* of timing is good for 30HP. If I had some more timing I should get some power I should easily feel. But Les you said you were tuned for 100 octane, leaded or unleaded?
