These plugs came out of my 440 fan motor after about 90-100 miles. Medium to hard ditch riding . I was in 15* weather. I have the carb set by the Poo high perf book for my altitude, and for 10-30* temps. Gas was 87 octane no ethanol (all I could find) switch set for cheap fuel.

I am thinking that if it gets ANY colder, then I am going to go to 320-330 mains. They are actually a little lighter than the pics show. So what do you think?

They look a little light......like White. JK try reposting the pict.

repost a different angle so we can see how far down the electrode is white...its like a fuse!once it hits the base...booooommmm
