Note:
5.
Do not inject after-run oil into the carburetor as
this may cause the O-rings inside the carburetor
to deteriorate. These procedures will reduce the
risks of starting difficulties or corrosion after a
period of storage.
Finally, when cleaning the exterior of the engine,
use methanol or kerosene. Do not use gasoline or
any solvent that might damage the silicone fuel
tubing.
Caution:
The rear crankshaft bearing of this engine uses a
special plastic retainer. If the front housing needs
to be heated to remove or replace the bearing, do
not allow the bearing to exceed 120˚C (248˚F),
otherwise it may be damaged and rendered
unserviceable.
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, 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.
