That plug MAY be one range too hot, but I doubt it.
The ground wire looks like the initial timing is almost to the curve and the total is at the base. The total is ok but it looks like it can use a bit more initial. Are you SURE a your timing light isn’t junk? Can you borrow a different one and check it?
I will borrow another timing light to verify mine is ok. A question about reading plugs. Do they need to be cleaned off after you make an adjustment to give you a good read on your new setting?
Or does their appearance just change right away after you two me the motor differently.
These plugs have not been taken out for a while, and I have had the timing all over the place recently.
