Change your name to "Techno Junkie". You've got the hang of it.
While you enjoy it so mutch, do it again.
Take another pic of the 152 so that the isolator is the same brightness as the 155. At this stage the colour of the 152 isolator is gray. Can't really tell that way.
I'm away for a couple of days. Im sure the rest of the guys will continue with comments.
Here's a pic with three WOT chops,
The left is with the 152main jet and the other 2 are with the 155main jet.
I was not able to stay in the throttle long on the middle plug, due to the D756 spinning and throwing me sideways as I was going from a paved portion to a dirt and gravel portion in 5th gear at WOT.
Color is indicative of plug temp, not (directly) A/F mixture.
It's the thickness of the ring at the bottom of the insulator that's the telltale of A/F. The darkness of the ring comes with more time. The lighter of wibby's plugs are about 8 sec, the darker about 15 sec.
But..it's the thickness or depth of the ring that's the issue. The 155 is still pretty wide. The 152 is pretty light, but it looks wide (not quite as wide), too.
Ok,, I think I understand now. So what we are trying for is a thinner ring. I was thinking just having a ring was what I was looking for, and I was very surprised to see one on the 152 plug.
So actually we need it to be more this plug below:
Am I Right? Closer? Please? No?
I'm tired of wrenchin' I just wanna go ride! :worship:
I used a Dremel rotary tool with a cut-off disc, well quite a few discs actually, until I figured out the insulator is a lot harder on the discs than the threads! :laugh:
