Well done

I noticed that drill size was stated as 10 mm, but the thread size is M10 x 1 mm. Shouldn't the drill size be smaller than 10 mm, or am I missing something?

Have you ever dyno'd a twin plug engine against a similar but single plug engine/? If so what was the result? thanks.

Yes I have. I was able to achieve the same power, on this particular engine, but after fine tuning the ignition advance to suit the two ignition types. Other engine will vary to the effectiveness of how many spark plugs per cylinder.
