Spark plug change

[Pogo]

I pulled my spark plug after I ran the buggy wide open for a couple miles. I guess I would say the colour was border line ok. But for sure it had been running hot.I could seel the colour and glazing on the insulator of the centre electrode. So I oppted for a one number cooler plug. Have run it now for a while. Not wide open but have pushed it really hard. The plug colour looks perfect. I think the buggy runs better?? For sure it starts better. I don't know what it will do to my top end but it is a fare trade off. It is a lot safer to run a bit cooler than hotter. Besides I haven't stated working on the motor or drive line yet. Just thought I would pass it along. May be helpfull to someone.
