Ok, I pulled the plugs today and got to looking at them and they seemed very good, dark tan. Then I noticed a couple tiny white spots on the electrode, so I tried looking down the plug hole to see if I could see the piston wash, not the best way. I could not see enough of the piston to tell what was happening, but I did notice a very clean spot right in the middle of the piston right where the plug is. This made me a bit nervous, so I did some searching on here to find some info.
I read a couple posts about the air and fuel screws, and got to wondering what the settings should be for my sled and when they talk aboout 2 turns out, I am only assuming that would mean 2 turns out from all the way in. Would adjusting either of these richen it up enough to take care of this potential problem I noticed? I guess my other option would be to jet up a size. I currently have 410 mains, and I think stock was 420, but 410 is what I had in there when I bought it used. The only other variable that I can think of is that I have been running ethanol fuel, 89 octane, which I am aware it has more Oxygen, but would that be enough to cause it to be running a little lean? Maybe I am over thinking this and just nervous, but I am leaving this coming Wednesday for a trip up north and want to make sure everything is on the up and up before I get there and have problems. Any help would be greatly appreciated and Thank You in advance. Rich
