Need some questions answered about a B magneto, trying to help dad get B running he just bought.On the inside it has dogs that catch a stud then release . It has 1 stud, but it has a place for 2. Is it suppose to have 2 ? Also in the book he bought it says to alighn the rotor with protrusion in upper left corner to install magneto. What protrusion are they talking about ? No pictures. Any help would be appreciated. Thanks

Jerry, I guess you would have a Fairbanks magneto.The mag should only have the one pin that when you set the mag in a vise and rotate in the direction the dogs catch keep on turning the mag should trip or click. That is when the mag fires. The other hole is in the case so the mag can turn the other direction. The spot in the cap would be where the tip of the rotor would point.Did you have the main cap off?The rotor gear would have a 'c' or'cw' on it look real close. You line that up with the small gear the tooth will have adot or the corner ground off.Your mag should line up to the 'cw' mark.Any question E-mail me Earl
