Sounds like you installed the magneto plate and didn’t make sure the cam follower on the carb was pushed forward to clear the cam. Pull the mag plate back off and push the cam follower forward as you re-install the mag plate. Also, when you install the mag plate, turn it so the small end of the cam is pointing forward – the follower will then be in front of the cam. See enclosed pic from my CD-11 assembly.
