Aloha from Hawaii, hope you all are enjoying the winter as much as me. Well my question of the day is, is it normal to get a partial burn on the plugs? put some NGKs in the other day and did a plug chop, well got a nice color on about a third of each plug but the rest of the plug was white as in not changed from new, any ideas or suggestions? I got a old sporty to put down and iam close [bout 25 or 30 feet in the 1/4] nice workin on an old air strip, still a lot of old bullet holes from the attack on pearl harbor and some 50 cal shell casings if you look hard, all in jap so can't read'em but cool anyways. I'am lookin for obscure stuff now,after going around this Island a zillion times. any help on the burn, different plugs, gas, I'am so close to putting him down and stopping the smack talk I can taste it need help.
