dangerous fire hazard that can cause loss of life and prop-
erty.
Engine safety
Before you attempt to start your engine, it is important for
you to be familiar with the correct method of shutting off
the engine when necessary. To shut off the engine, use
needle nose pliers or a surgical hemostat clamp to squeeze
the fuel supply line closed. The fuel supply tube is the
clear silicone rubber tube that connects the bottom of the
fuel tank to the carburetor on the engine. Squeezing this
tube closed for a few seconds is the
only method you
should use to stop the engine safely.
Do NOT remove the fuel tube, or attempt to stop the en-
gine by touching or holding any part of the engine, trans-
mission, or wheels! Do not use your fingers to squeeze the
tube because you can be burned by touching the very hot
engine or exhaust system. Wrap several layers of thick
tape around the jaws of the pliers or hemostat to prevent
cutting or damaging the fuel line.
Fueling
The Tempest Gladiator is equipped with a competition
fuel tank and priming system. The fuel tank uses a spring-
loaded filler cap over a wide filler neck for fast, easy fuel-
ing. Simply pull the cap open and it springs back closed
when you remove the nozzle. Use a fuel filler bottle with
an attached long nozzle that can be inserted into the filler
neck. Do NOT pour fuel from an open can into the tank
or attempt to use funnels or loose parts to fuel your truck.
We recommend Megatech’s “High Velocity” 25% Nitro
fuel, or other premium quality car/truck fuel with 25%
Nitro content.
The fuel tank is equipped with a primer pump to allow
easier and safer engine starting. The primer is located on
the top of the fuel tank next to the filler cap. To prime the
engine, fill the tank with fuel, close the filler cap, and
press the spring-loaded primer 5 to 8 times until you see
fuel pushed through the fuel supply line all the way to the
carburetor. Then press the primer two more times only, to
inject a small amount of fuel into the engine. The fuel line
and engine are now ready to start.
Engine break-in
Important! For the best performance, maximum enjoy-
ment, and longest service, your Megatech M-16 engine
must be properly broken in before you adjust the engine
for maximum power. The M-16 is a close-tolerance, preci-
sion machined engine, which needs to be broken in so that
the matching surfaces and parts establish the correct run-
ning tolerances. Proper break-in during first few tanks of
fuel determines how well your engine will run for its en-
tire life.
This is an easy process that requires only three full-tank
engine runs at reduced power settings. Only
after the
break-in period can the engine be adjusted for maximum
power. The break-in period is also an excellent opportu-
nity to get used to driving your Tempest Gladiator and
become familiar with the truck’s great handling qualities.
Break-in Settings
The M-16 engine is adjusted at the factory for the correct
settings to break-in the engine. If for some reason you lose
the settings, close both the high speed and slow speed nee-
dle valves (clockwise), then
open the high speed needle valve three full turns
(counter-clockwise), and
open the low speed needle valve four full turns
(Important! Do not force the needle valves closed firmly;
only close them until you feel slight resistance)
