I have almost 1000 miles on the 250 now. She's running good ftmp. Choke is sticky from 3/4 to full closed. I pulled these plugs today after a good highway run of around 15 miles. I could put all I know about spark plugs and reading them on one of those mini post-it notes so I could use some help. They look pretty good to me, maybe lean? They all pretty much look the same. The heat band on the ground straps comes to within at least 1/16 to 3/32" of the body on all of them, some go all the way to the body. The pictures are a little screwy b/c of the led I was using for light put bands in the pic. Any insight is appreciated. These are Autolite 45's, I pulled them today to look at them and install some 44's I picked up.

You can see in the last pic that the heat band on the ground strap goes all the way to the base on #3, #2 is very thin and #5 is just a bit higher than #2
