Hi everyone,
I recently purchased a secondhand MP40, but when I got it home, it was making a loud, harsh noise. I took it apart and discovered that the internal impeller is rusted out. Unfortunately, the seller from Marketplace has not responded to my messages.
Has anyone successfully repaired an MP40 with this issue? I would appreciate any advice or tips on replacing the internal impeller. or if this should just go in the trash
