Re: Roto stop serial number
Honda 216 4vxa serial number is MZCG 7760688
That serial number is showing up in my database as a HRR216K4TDA, not a VXA.
The TDA does not have Roto-Stop.
But, if you do indeed have a VXA, it will have a yellow lever for the RotoStop on the right side handlebar. Some of these units can 'release' the blade control unexpectely, due to a improperly shaped blade control lever. Your serial number was made well after a fix was implemented at the factory, but your mower can exhibit the symptoms.
Drop me a private message WITH YOUR EMAIL address, and I'll send you a copy of the bulletin as an FYI; you may find it useful to look ever
