Nitrous on a 340 100 shot
Cylinder #1 is the first 2 pics
Cylinder #3 is the 3rd and 4th pics
Then took another 2 pics of a plug after I got home from being stuck in traffic and idling a lot. Seems really dark and almost wet, even the porcelain is dark now. Does that mean my plugs are too cold? Or is it because my initial timing is so low? I could change my curve to a 15* sweep that gets total timing at 2500rpm so I would be 17-32 instead
Took the car out for another hit of nitrous today and snapped a pic of the fresh plugs that are one heat range cooler, and turned my timing back one more degree to 32* total and 12* idling. took the pics right after I gave it a nitrous hit to 3rd gear.
