The Super Tiger carb is just a little different than most other carbs. The high-speed needle controls the fuel flow at wide-open throttle the same as every other carb. The low speed however extends inside the fuel spray bar and works by partially blocking the cats� eye slit in the fuel spray bar. As the drum is rotated the low speed needle adjusts its position inside the spray bar to regulate the fuel at idle and mid range. Mid range can also be adjusted somewhat by the rotation of the spray bar and the cats eye slit in the spray bar.

First lets start at the beginning.

Set up of idle screw. Close the high speed then open 2 and � turns. Use a short 6-inch piece of fuel tubing and put on end over the fuel inlet. Use a pin (t-pin or building pin) and close the throttle barrel until it just contacts the pin. Roughly 1/16 of an opening of the carb. Now blow through the tube and close the low speed until no air will pass. Slowly open till air will just pass. Now open � to � turn more. Your low speed is set to factory specs.

Replace the glo plug with a Hanger 9 HAN 3000 performance two-stroke plug. These may have been discontinued so use the HAN 3006 or the Heli performance plugs HAN 3020. One other trick is to take a small screwdriver and pull the element so that it is slightly extended beyond the base of the plug.

Start the engine and set the high speed. You can use the pinch and release method here. Pinch and release the fuel line. If engine sags or dies you are to lean if it speeds up its too rich. Do it a few times to confirm the result. No rpm increase indicates this is as lean as you want to go. Some will open the high speed till a very slight rpm drop is noticed and that�s about it.

Set the low speed as you would any other engine. If the mid range is a little off try rotating the spray bar and cats eye by loosening the two screws that hold it in the carb on the high speed side. Rotating the cats eye will change the mid range.

Using the pinch test check the top end rpm often as some of these changes may effect the top end as well.

Hope this helps

Dennis
