I tried installing a new magneto from Zimmerman's and it won't spin. I thought I may have bolted it incorrectly but I'm sure it's right. I took it off again and I noticed that the female part in the governor which is supposed to connect with the male part in the magneto moves in and out, slightly. I'm thinking that the play in the governor isn't allowing the two parts to connect. Is it usuall for the part in the governor to move in and out? Or, am I doing something wrong?
i had the same problem...the gear does move in and out if the spring is not tight....check the spring between the two governor arms. I had to tighten my spring and re time it. Now runs good.
