  If you can't turn the engine over using the pull-starter, don't force it.

The engine is probably flooded.  See the warning and resolution on the previous page.

❑

Connect a fully charged glow starter to the top of the glow plug, making sure that the

glow starter is locked firmly onto the top of the glow plug.  You don't want it to fall off while
you're trying to start the engine.

❑

While holding the truck with one hand, carefully pull on the pull-starter cord using short,

quick pulls, until the engine starts.

❑

After the engine starts, release the pull-starter cord, allow the engine to run for about

10 seconds, then remove the glow starter from the glow plug.

  If the engine does not start after a dozen pulls, refer to the trouble-

shooting guide starting on page # 16 before continuing.

❑

To stop the engine, carefully pinch the fuel line with your fingers until the engine stops.

Make sure to pinch the fuel pick-up line and not the fuel pressure line.  The fuel pick-up
line is the one connected to the carburetor.

WARNING

✦

✦

✦

✦

✦

  Be careful not to touch any parts of the engine or tuned pipe because

they will be hot.

Fuel Recommendation:

Fuel can make a big difference in the way your engine performs.  For the break-in period you should use a fuel specifically designed for
R/C car engines that contains no more than 20% nitromethane.  Once the engine has been adequately broken in (about 45 minutes of
run-time) you can switch to an R/C car fuel containing up to, but no more than, 30% nitromethane.

WARNING

✦

✦

✦

✦

✦

  We do not recommend using fuels designed for R/C airplane engine use.  These fuels do not contain the proper

amount of lubricants; therefore, they will cause the engine to overheat and severe damage to the engine will result.
