Hmmm, if the mag plate is being dragged back to idle, you may have a few issues going on.
First, someone may have removed the friction cup and spring from underneath the tiller grip.
Second, Perhaps you have not properly aligned the coils on the mag plate, so they are rubbing on the flywheel magnets
Thirs, that mag plate seems kind of loose/jumping around a bit. This might create excess sideways slop allowing the coils to hit the flywheel, point gap will be erratic as well.
