This saw has the same displacement as the Remington Super 990, however it was made by Mall, making it a prototype to the famous Remington Super 990. The model number on the serial tag just says “Mall Saw”. This saw has much more aggressive (open) porting than a Remington Super 990, and it has a custom made exhaust deflector (not even worthy to be called a muffler). This is by far the loudest saw I have ever heard, and it is by far louder than a Stihl 090, Tecumseh AH-81 (with strait pipe). It’s far louder than any McCulloch or Homelite could ever hope to be. It’s even louder than my West Bend 820. I can feel it idling in my chest while I’m standing 10 feet away from it. This video does not give a good example of how loud this saw really is. 105cc, 12″ NOS bar, .404 chisel chain.
