The only time I had aplug that rusty my copper head gaskets were leaking. Put new plugs in and try again.a leakdown test would be a good idea too.Looks like its detonating some too.it could be lean , like Curt said, or your timing is off or.... Question

The center electrode is awful sharp on the edges, he ain't hurting anything, but the rust is something to look into.

I've seen them rusty like that after it sat all winter. I would say any idling with a 3 circuit will get the plugs black in a hurry.

I put it on top dead center/compression stroke.... with a piston stop and the pointer was dead on with 0 on balancer...Would have to be the timing light if anything....

Put fresh plugs in it and start over imo.

If its been run off and on and allowed to sit your gonna get condensation in it...... Its not just an alky problem lol.

Powerstokeace is right. If I make a nitrous change I click it off at the stripe. Coast back around and get pulled back to the pits. Pull all the plugs, put them in the holder by cylinder #, get them on the bench under the lights and check them with the plug reader (light). One thing I can say about this is ask 5 people at the track to read your plugs and you will probably get 5 different answers. For plugs a little fat is good if you are trying to be safe.

I see how Frank does it, it works for him but no way Im runnin my shifter back over all those gears to get to neutral, I have a glide so its a non issue.

I also think Frank uses an alum drum in his c6 so its not as critical when the thing gets slung into warp speed.

There comes a time when you need to upgrade to a proven racing part. The PG is one of those parts if you're not using a clutch.
