Tightening the screw weakens the air and fuel mixture and decreases the amount of fuel flowing to the engine. Adjusting the mixture screw out to far will result in an overly rich fuel mixture in the low RPM range. Note: if the screw (C) has a square head instead of a flat blade slot, this takes a tool designed just for this purpose.

Back in the days when carburetors were used for mixing and passing the air-fuel mixture to the intake manifold, idle speed was controlled using an idle speed screw. 3. Hold the position for about 10 seconds. Compare . Running a lean fuel mixture makes the engine run with less fuel than it needs to run efficiently. Hissing sounds will be made. I replaced the spark plug with a like for like new one along with air filter. The spark plug normally fires anywhere from 10 to 45 degrees before the piston reaches TDC, to allow the fuel/air mixture's flame front to traverse the combustion chamber. This means that for every 1 gram of fuel, theres 14.7 grams of air. Figure 2 Exhaust: The MINI R56 N12, N16 and N18 engines utilize two VANOS (variable camshaft timing) solenoids -- one for the intake camshaft (green arrow) and one for the exhaust camshaft (red arrow), mounted to the front of the cylinder head. An extremely lean adjustment will cause the engine to die, too. If you are having trouble starting the engine, put fresh fuel in the tank and try again. Step 2.

Then, inspect them carefully for wear. Tuning by ear or with a vacuum port are effective ways to determine running condition, but don't actually read the air-fuel ratio. This fuel then makes its way through the system and could cause a backfire. I use it diluted 1:1, so the mixture is approximately the same concentration as the OEM. 2 Cycle engine: Tools required: Ratchet with 6 extension, 10mm socket, 10mm socket wrench, flat blade screwdriver, and a feeler gauge.

Compare . Torx blade TX27 and 19-13 and 19-16 spark plug wrenches. I adjusted the idle mixture screws and the best reading I got was about 17-in-Hg. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. Remove the air filter and clean it with compressed air or by washing it with soapy water. Over tightening can damage the tip of the screw so that proper adjustment is no longer possible. The filter doesn't need to be cleaned until an appreciable drop in power occurs. The mixture screw or EZ-Just is the key to proper tuning. Tightening the screw is also called making the fuel mixture leaner, which lowers the RPMs at which the engine idles. These compounds have a very high combustion temperature and are capable of burning without the pressence of oxygen. Adjusting the idle mixture screw out to far results in an overly rich, low RPM fuel mixture leading to poor gas mileage and carbon buildup in the combustion chamber. High Speed Fuel Adjustment (marked H on carb, this is the high speed jet) This is the adjustment that controls the proportion of fuel in the combustible air/fuel mixture at cutting speed. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. Start the vehicle to set the mixture.
