RE: New Engine Break In
I bet the spark plugs were trying to tell you smoething, and it wasn't just to change them either. You had a serious problem there. I just came back from Gregs, and we discussed this topic, and even pulled the at least 4 year old origional plug out of his Brison. It looked great ! The center insulator was a nice tan, and the plug was very clean. No material was even close to being disfigured in any way. There was a small amount of black buildup on one side of the outter ring, but it wiped right off with a finger, and thats after being in the Brison 50 for over 4 years ! The appearance of the plug tells me that the engine has never been overheated as well. Im willing to run exactly what he's been running, and thats 100:1 with QuickSilver full synthetic. I aint gunna argue with success like he's had with it. The plug don't lie, and i've been reading spark plugs most of my life as a professional mechanic.
