Hi,
I've been trying to sort out a miss/stumble at light throttle. Done a link & sync & tuned the carby to what i feel is a pretty good setup.
This has made the power delivery nicer, shifted the stumble lower in the rev range & has seemed to reduce the severity.
Now i want to replace the plugs/points & check the leads & coil.
From what i've read i need to use either champion J4J or J4C or NGK B6S or B7S.
My question is: the plugs in it at the moment are NGK B9HS, is this a good plug to be using or could be causing issues?
