To do this, push a length of about one meter silicone tube into the socket of the mixture (input section of the pin of the maximum), having previously removed the carburetor from the engine crankcase. Unscrew completely (Make up to 5 / 6 speed, otherwise you could unscrew the pin with the consequence of losing the O-ring in the body of the pin) of the pin up and blow forcefully into the tube to verify that there are no foreign objects entering above. After opening, manually, the butterfly air, close the needle up until, by continuing to blow, we realize that it will not be any more air from the tube.
Having thus found the fully closed position, we will open three rounds of the pin up until the blown air will correspond to 50% or less of what would pass with the needle fully open. This, for a car modeling expert does not represent any difficulties for the uninitiated it may seem difficult. In fact the nearest request is not so important, but you will also avoid consuming the wheel of the tool or use the pull start again in vain attempts to start if the pin was too close. If in doubt then that abound in short supply.
The second thing to do is to adjust the minimum bar of the manual, so you rely on my post on the carburetor. The adjustment
Finally, the minimum needle (nozzle) is getting his mouth, but aspiring, not blowing as the maximum.
A closed throttle (ie flush with the slightest mechanical that will leave a slight gap) we aspire to with some effort: if it does not move the needle, unscrew the idle air (spray) until you feel a small stream at the intake. The preliminary carburizing is complete. Now we have to replace the carburetor on the engine case and proceed from step 5) of my post.
If your engine starts immediately, then you only need to take care of the settings from step 10). If not then, alternating with a goodwill adjustment, loosen the 1 / 8 turn at a time before the high-speed needle, then the joke of the last and only minimal mechanical sprayer. Once the engine is started and remains so, individually, from point 5) of my post on the carburetor.
