Engine miss firing after warm-up

Cheack tappets,cheack points gap.On both these i go a bit more than the book as this new fuel is a bich on valve seats and plugs.Best idea is to go hotter on your plug.This burns off crap on the electrodes.Dont concern yourself on buning holes in pistons as your not racing around at 6 to 7 thou RPM.

G'day sogytrype.
You are correct in that a hotter plug burns the modern crap I mean fuel a lot better. I get best results with B6ES but I wouldn't go any hotter than a B5ES in the A7. I still use B8ES in the cafe as she does see 6-7K often.
Cheers
