Well I have been using feeler gauges to set plug gaps since 1959 and have never had any issues.

I run no gap, i only run brisk multispark plugs (a true multispark plug,not a 3 electrode plug) after seeing the dyno result on my own cars. Worth their price imho.

did you compare to ngk plugs on dyno
The mini was VS ngk plugs, the mustang was VS AC DELCO plugs
what was the difference on the mini in hp and what brisk do you use. the cone lookìng brisk I tried coil couldnt cope and drove like 998
The difference in hp was negligible , 2 HP if I recall right. Torque curve was a lot smoother,and higher from low rpm.

Dr14zc if I recall right, I should take a look in my paperwork,its a few years ago now
what ignition was you using. yes those the plugs I tried bit had no go to it brisk said for better ignition cars

The powerspark ignition module with the sports coil on the mini, new leads etc as well. Indeed need a very good ignition system for it!

Also they are called feeler gauges because you can feel when the gap is correct!
