So when I received a large number of manuals, that I saved from the tip, I also received some individual pieces of information sent to victa this dealership about the hi-torque 6 engine and how it produces its %15 more power. Information on tweeks to the the G4 and LM carbys to help them perform better. Also some changes to the original Victa Twin engine design that were made to fix issues with the original engine design.
