What brand plug is that. It makes a difference in how it reads.
If that is an NGK and its changing color 4-5 threads down that plug is 2 ranges too hot.
Also, remind me what fuel. If it's pump gas, the timing is too slow, probably because the plug is too hot. It's hard to see in those pictures. Cut a shell off of the plug you think is the best so we can see the fuel ring and better see all the porcelain.
Edit: either not enough timing or you have a bunch of initial and too much total. Damn I just don't see enough in those pictures. Old eyes suck.
