  • Page 2: How To Start Your Engine

    RB Concept engines instruction manual Thank you for choosing RB Concept. The nitro powered engine you have purchased has been designed and developed by former World Champion Rody Roem. Manufactured with the most advanced machines, with great care and precision, this engine is the highest quality product available.
  • Page 3 FUEL Only use commercially available fuel formulated for model car engines. It is advised to use our RB Concept Fuel whenever possible. In the event you cannot find RB Concept Fuel we suggest that you follow the recommendation of your dealer where you have purchased your engine.
  • Page 4 the quality of the fuel and increase the potential of corrosion forming inside the engine. We suggest not using fuel that has been unused for 6 months or longer and also we strongly advise not leaving unused fuel inside the engine when you are finished using it.
  • Page 5 CARBURETOR There are 2 types of carburetors, «SLIDE» or «ROTARY», the adjusting principals of both carburetors are the same. The carburetor supplied on the engine is preset at the factory, meaning that the original settings are close to where they should be for normal operation. On the carburetor you can find in general 3 to 4 adjusting possibilities depending on the carburetor supplied with the engine.
  • Page 6 IDLE NEEDLE 2) The idle needle controls the amount of fuel going into the engine when the throttle is fully closed. Turning this needle clockwise makes the fuel mixture leaner, and turning it counter clockwise makes the fuel mixture richer. IDLE AIR SCREW 3) The idle air screw adjusts the opening gap when the throttle is in the closed position and determines the idle rpm.
  • Page 7 If the glow plug driver cannot make the wire glow brightly, then replace or recharge the battery. When possible use only genuine RB Concept glow plugs, since these have been extensively tested and approved for the maximum performance...
  • Page 8 EXHAUST SYSTEM The exhaust system consists of a manifold and a pipe. The exhaust system has two functions, to optimize the engine performance and also to lower the noise level. The noise level is determined by the number of chambers used in the pipe, while the performance characteristics are determined by the shape and length of the pipe and manifold combination.
  • Page 9 flat. This is important to avoid any distortion of the crankcase and also to optimize heat dissipation through the chassis. Tip: To flatten the bottom part of the engine mounts, attach the engine mounts to the engine, and then rub the bottom of the mounts on a piece of sandpaper on a flat surface until there is full surface contact.
  • Page 10 3) Turn the flywheel with the help of your starter box (do not apply the glow plug driver) for about 3 seconds or when using a pull starter pull 4 to 5 times so the fuel goes through the engine. When using the starter box you will notice an increase of rpm, this means the fuel is going through the engine and lubrification is making things easier.
  • Page 11 Tip: When the piston/sleeve is still new the fit can be very tight and so at first starting the engine can be quite difficult. To make this easier, you can heat up the engine with a hairdryer before starting. If the engine fails to start… ·...
  • Page 12 2) After the engine has run at idle for 125cc, you should let the engine cool down before restarting it (be certain that the piston is not stopped at TDC), and open the main needle for at least ½ turn more than it was originally set.
  • Page 13 If however you prefer to try yourself, here is how: Attention: Work only on 1 carburetor adjustment at a time and make only small adjustments, maximum 1/8 of a turn! Pre adjustments. Once the engine is started let it reach operating temperature, then proceed as follows: 1) Set the main needle by holding the car off the ground, then open throttle completely.
  • Page 14 4) Set the idle rpm by using the idle air screw, and try to find a low but reliable idle rpm. A too high idle rpm makes it more difficult to slow the car during breaking. Attention: When adjusting the idle needle, this then can effect the idle rpm, use the idle air screw to adjust the low rpm when it becomes too high or too low.
  • Page 15 Once properly adjusted, the engine should produce a strong, high-pitched sound at maximum speed, and a thin trail of smoke should be visible from the exhaust tailpipe. NOTE: The carburetor settings may change with changes in weather conditions, fuel, glow plug or exhaust system. After changing any of these, always richen the main needle ¼...
  • Page 16 inside the engine after each day of use. To be sure, we suggest you start the engine, let the engine run, and then pinch the fuel line until the engine stops. We suggest that you check the internal condition of your engine on regular basis, and if you are not familiar with this then we recommend that you ask your LHS or Dealer where you have purchased the engine to help you to check the overall condition of your engine.

  • Page 18 Cautions · Dirt in the engine is by far the most common cause of major engine damage and voids your warranty. The air filter must be used all the time and be properly fixed to prevent dirt from coming into the engine. Also be sure to change your air-filter on regular bases depending in what circumstances you use your engine to prevent dirt from working its way into the engine.
