Pull the motor assembly outand trim the beam plate to assure that when the motor torques it clears thebeam plate. Check and be sure to trim the beam plate at the motor mountattaching points to flush with the motor mount, i.e. don’t leave beam platewhere it can damage the rubber of the motor mount (Hyde YS type) as it moveswhen the motor torques.
Once the trimming is complete, install the motor assembly,prop and spinner and be sure all is aligned properly and satisfactory.
