Sounds like the Powertorque spigot should stay on Norm ,I was thinking it may have been a loose fit and the JB weld
would be taking up the slack.
I have always found the round Mayfair blade plate makes the motor run smoother than if you fit the oval powertorque
blade plate as long as the blade plates aren't bent or damaged.
The round cutter plate must be more dynamically balanced compared with the oval plate.
