Then you are probably lean. It sounds like the plug is almost partially burnt up and ashy......

Here is where i have my temp thing at. I have it facing away from the header, so no extra heat can throw it off...

I solved it. It's a maxx. If that motor were in a revo it would run perfect and then just blow up randomly. Mine didn't spend any time jerkin' me around. :-D j/k

I agree. Grey and distorted sounds lean. It is hard to tell, completely, since the engine hasn't JUST been run, so it being dry really doesn't tell much. I would assume that if it was too rich, the plug would still be oily, but it may have dried.

Isn't pitting caused by detonation? (Lack of shims, TOO high Nitro content, etc.)

Believe it or not, it is actually more acurate with the sensor located above the Exhaust port. It get's it's readig from the contact point and isn't really affected by the header (as long as it isn't touching the header)

Yes pitting is caused detonation. too high nitro content with too small of a combustion chamber

the pitting can be caused by lean settings or low deck height

You couldn't tell it was a Maxx from the first pic? The header came off the back, and around the side. Are you sure you didn't hit your head... JK Dan, Hope you have a quick recovery.

Funny I would mention the TOO high Nitro. Everyone thinks I'm crazy for running 40%. I tried adding a shim, and it didn't run as good.

i check for the macro thing, and my camera does have it, but for some reason when the light hits the metal it makes it blurry , i'm not sure why

Yeah.... I don't think it's too hig of nitro content here. I am going to go with the fact that that sensor isn't off by that much and it has been run lean for some time now. If it were rich, even if it hadn't run in a week or so, the plug would still be oily. That isn't the case. My vote.... Lean.

It's focusing on the flash. Turn off the flash, and hold the plug under a regular light. Also, don't hold the camera too close. Turn on the Macro setting, and use the Zoom to get the close up.

Work it.... work it...... there!

Just trying to help...

well, i appreciate teh help everyone. But form what i ahve read, i'm not really sure what to think. Everyone has thier own opinion. Tomorrow i will try to re-tune from scratch and see what happens.
