[Healeys] Spark plug gap

[lists]

Hi Simon,

standard plug gap is more like .7 or .8 mm. I wouldn't widen the gap to more than 1 mm with 123ignition.

I have a BT7 MkII with 123Ignition & a Lucas Sports coil.

On the engine side it has 3 HD6s, a 6 branch big bore exhaust, and a Denis
Welch fast road cam.

 

What spark plug gaps do you experts suggest? (I'll be running NGK's BP 6ES
plugs).

Thanks,

Simon
