Do these look OK?
I haven't been reading spark-plugs since my dirt bike racing days. On my bike, those would have indicated a slight lean condition. (IMG:style_emoticons/default/idea.gif) What about a 993 3.6L motor? Still too lean? Or OK? (IMG:style_emoticons/default/confused24.gif) Andy Attached image(s) |

...............ANYTHING that WHITE is too LEAN.....look closely and you will find hard /melted/fused ..deposits....the plug tip is so hot it,s melting....Richen up the mixture before you burn a valve, hole a piston, or worse.........(needs a little more brown color to get "normal looking".)......and as mentioned check the oxygen sensor, a old or defective one will alter fuel mixture..+.check fuel filter..+..did you add race gas or an additive , drive awhile , before pulling plugs?........Ideas to consider. the chart in an earler post is Identical to the CHAMPION spark plug chart and is an excellant referance for spark plug condition..........
