Dark brown plugs\semi melted electrode?
Have about 1100 miles on new engine. See sig. About a week ago it started acting up. Harder to start. Will idle for about 45 secs. to a min. Then die. Had autolite 25's in it. Pulled them all, and they were a dark chocolate brown. and the little tip, or electrodes, were a little rounded. Ran to parts store and bought the Autolite 65's. Also a new cap, rotor, and cleaned the K&N. What is causing this to happen to the plugs guys? Am I using the right heat range on the plugs? Also, I've noticed that most of you guys in here are running on average, between 32 and 38 lbs. of fuel pressure. I'm at about 45 lbs., vacuum line off reg. of course. It won't idle worth a crap or even run below 36 lbs. Any ideas on these gremlins guys. Sure is appreciated largely. Peace.......
