well I found someone to rebuild my starter for my boomer 30, I recommend Highly
Larkin Electric
P.O.Box 1044
Hamilton city ca. 95951
They specialize in alternators,starters, and electric service
I took my starter to them and they fixed it right away... old style service, they rebuild them right there, as I understand they are the only ones in Northern California still doing so appears there is not much they can't fix, decent pricing as well
