Yet another spark plug query

Recommended Posts

Was out in the car today, went to give it some and it had a misfire. (never done that before).

Have got the NGK BKR7E fitted and gapped to 0.8mm.

Would i be better gapping it to 0.7mm or better going for the colder grade BKR8E gapped at 0.7mm?

Also noticed it doesnt start aswell as it should (turns over longer before firing)

Am running at 1.2bar with 650cc inj, HKS 264 cams with emange.

 

Thanks
