Spark Plugs

[Guest]

My Grand Daughter has started racing in Novice with NBRA. We have a Yamato 102 with a restrictor plate and was wondering what the ideal spark plug might be. Currently were running NGK B9ES plugs and they appear to be a bit to cold in that they are black after a run. We mix the fuel at 24:1.

Ngk......

For your purposes you are running the right plug and fuel mixture. Maybe lean the carb down a couple clicks to get a lighter color on the plug.........
