[. . . ] The stamped number on the lower part of the jet indicates the measure of the hole that calibrates the petrol flow. A bigger number corresponds to a bigger hole and more petrol flow. WILD HP -100- WARNING Petrol is highly flammable and can explode under certain conditions. Always stop the engine and do not smoke. Make sure the area is well ventilated and there are no spark or flame sources nearby (including a lamp). (B) (A) (C) Carburettor needle (A). Idle jet This jet controls the mixture from the closed position to 1/8 of the throttle opening, but it has little effect on a fully-opened throttle condition. To adjust the idle mixture, the air screw can be turned to change the air flow or the idle jet replaced so as to allow for more or less fuel to enter the carburettor. We must always turn the screw from a predetermined position. If you turn the screw from 1-2. 5 turns and the desired result is not obtained, change the idle jet (C) and fine-tune using the air screw (B). The needle and the needle jet together must have an effect from ¼ to ¾ throttle. The needle moves in and out of the jet, and the tapered end of the pin determines the amount of fuel that is let into the carburettor. The top end of the needle has five slots where the clip is fixed. The clip places the needle in the throttle valve and determines the relative position of the jet, and so the mixture is enriched. Moving the clip to the top of the needle makes the mixture poorer. The straight part of the needle affects the throttle valve response to small throttle movements. Clip position Needle size number Working area WILD HP -101- Test with your vehicle - Warm the engine up with the carburettor in the standard settings, and examine the spark plug condition. - Test the quad keeping the carburettor valve open.
