Quite often, the carburetor starts to make a loud noise in the car, and it feels like the car is about to fall apart. There is a high probability that this is due to poor valve alignment or a gap between the engine valves. One of these valves launches a combustible mixture into the cylinder, while the other at this time releases all the exhaust gases. Moreover, the mechanism of the valves and actuates them, and also sets the required interval and order of their operation.
Instructions
Step 1
After the engine heats up, all of its constituent parts expand greatly, as a result of which gaps appear between the valves, which must be properly adjusted, otherwise the malfunction can lead to a gradual decrease in the efficiency of the overall operation of the entire engine.
In order for you to check and start adjusting the valve, it is necessary to disassemble a part of the engine in its cold state. Then you need to take a flat dipstick, with which you can easily feel the thermal gap between the valves.
Step 2
After you find this gap, you need to adjust its width by turning the adjusting screw on the rocker arms, or a special head of the adjusting bolt in the desired direction.
Step 3
Then you can start the valves, which you set at top dead center for the compression stroke of the cylinders. In this position, both valves of your engine will be closed, and all the rocker arms of the cylinder valves will swing freely within this gap.
Step 4
Then you can lower the locknut into the gap and use the adjusting bolt to set them in a horizontal position, without changing the width of the gap. Tighten the lock nut immediately, otherwise your result will not be secured. After that, you can restore the entire cylinder structure in the engine and check the noise in the engine by turning the crankshaft half a turn.
Step 5
Thus, if there is no sound in the engine, it is safe to admit that you yourself repaired the engine and were able to adjust the valves on the cylinders.
