         This is the O.S. Max 18TZ Turbo Engine with Recoil Starter
                         and 11L Rotary Carburetor.

FEATURES: Oversize case fins dissipate heat to keep engine temperatures lower
          Five port cylinder liner for increased air flow
          12mm rear bearing lessens vibration and allows engine to handle more
           torque
          Rotary carb
          Small diameter recoil design for easier manifold installation
          Super-hot turbo P3 glow plug for more power and improved fuel economy
          Rear exhaust with a round port
          Two-piece head design (inner head or head button and outer head)

INCLUDES: One 18TZ turbo engine with threaded shaft, 11L rotary carburetor,
           P3 glow plug, exhaust seal o-ring, drive washer and instructions

REQUIRES: Muffler (exhaust system) depending on vehicle
          Starting equipment
          Fuel: 5% - 20% nitromethane content
             Most of the fuels we carry meet or exceed the lubricant content
             required for maximum engine performance and long life. In the past
             conventional lubricant content used in fuel was 18%. But with new
             advanced technologies, fuels like Red Alert and O'Donnell have a
             better quality of lubricants even thought the percentages of
             lubricant content are lower. These high tech lubricants provide
             exceptional cooling and protection.
