Spark plug reading

[Walkeracing960]

I have a 2000 GTX ME 951. I'm having some issues with it but I have a question about my plugs. Do they look okay or lean? Thanks

I think they look slightly lean. I believe the center electrode should be a tad bit darker. Almost like a dark tan. Hopefully someone else can confirm.

I would like to see it darker if it were mine.

 

[Walkeracing960]

Do these look any better guys?

 

[mikidymac]

Nope.

Would turning the low end screw help any. The carbs were just rebuilt.

 

[mikidymac]

The low speed screw only effects idle.

Any better?

Any better?

Yes, they look better but I would like mine a little darker just to be safe.
