Title: Spark Plugs
Post by: Metalorama on January 30, 2013, 01:44:26 PM
Hi all, I know this is a common topic and I have done searches on it (before anyone lynches me :chat) Currently my FD has the standard plugs, I was reading that it\'s common to run all four as BUR9EQ(P) especially when modded to higher boost, which is fine.

What I can\'t really find any info on is that I am running no OMP and 100:1 premix and I just wondered if I use four of these if they are going to foul all the time due to them being a colder plug. My concern is that the hotter plugs help with combustion of the 2 stoke, but if I replace them with the cooler plus they won\'t burn it off and they will just foul.

Anyone have any thoughts?

You be fine dude, I run my daily Silver FD with premix no omp with 4 x 9s for the last 10k , has not fouled up or failed to start once, even in the cold weather we had

Good to know, cheers! :D Couldn\'t find a damn thing about premix with these, a good bit cheaper to run four of them rather than two and two, which is handy since they\'ll be changed regularly.
