Welcome to AS, Bert. I'm in Madison. PB definitely knows his stuff so hopefully that will you back up and running!
Well, some things I know but the coil on the 910 I am not so sure. I am pretty positive that later 900 series saws shared ignition components with the 288 but I am not sure about the 910. Spark plug coils are the same on the 451, that i know for sure. As long as the 451 has the same ignition system because there are 3 different versions.
