Step By Step Guide To Starting Your Nitro RC Car

  • Charge glow starter for 5 hours.
  • Fill fuel tank with 12% to 30% nitro content model car fuel and make sure the fuel tank lid is fully closed.
  • Prime engine by positioning throttle to fully open position, plugging exhaust with your finger and pulling pull-start until fuel enters carburettor and 2 extra pulls to complete priming (remember to return the throttle to idle position for starting).
  • Attach glow starter to glow plug and pull pull-start. The engine should start within 1 to 12 pulls (you may need to give the engine a small amount of throttle as this can help the engine start).
  • Don't be afraid to leave glow starter on glow plug if it helps the engine run (if it does help the engine run than your carb setting is probably a bit rich and should be adjusted by turning the low speed needle clockwise by quarter of a turn (please see Manuel).
  • If pull start becomes very hard to pull and the engine will not run. This means the engine is flooded. You will now need to disconnect fuel Pipe and plug it. Remove glow plug from cylinder head, hold car upside down and pull pull-start a few times to clear any excess fuel. Now refit glow plug (not to tight) and fuel line and see if engine will start without priming (step 3).
  • If the engine still won't run after repeating these steps a few times. Please check the glow plug is working by removing the glow plug, attaching the glow starter (heater) to the removed glow plug and checking that the glow plug is glowing hot.
  • Check the carburettor setting is correct. The factory setting for the high speed screw is 5 turns out from fully in and the low speed screw 2 and ¾ turns out from fully in. These adjustments should be carried out by a experienced RC user, as incorrect settings can cause the engine to overheat and damage.

Hot Tip
