GUARANTEE
This engine is constructed from the very
best materials available and to the very
highest engineering standards, using
the most advanced precision machinery.
However, the extremely high stresses
imposed by car racing operation under
very severe conditions, as well as
stresses which are exacerbated by the
use of powerful fuels containing very
high concentrations of nitromethane,
constitute hazards which are beyond a
manufacturer's control. Accordingly, we
regret that it is not possible to extend
our usual warranty terms to this
particular engine -i.e. no guarantee is
offered against material wear, or damage
resulting therefrom, in actual use.
As delivered, the engine has the
carburetor lightly fit into its intake.
Secure it changing its angle according
to the car chassis.
NOTE
Please do not run on a public street, this
could cause serious accidents, personal
injuries and/or propetry damage.
Please do not run near pedestrians or
small children.
Please do not run in small or confined
areas.
Please do not run where loud noises can
disturb others, such as hospitals and
