CLUB OF CAR FANS
A touching moment: a thoroughly repaired engine once again settled under the hood of Tavria. "Antifreeze" and oil, gurgling, spread over the systems. The carburetor body, having swung the brand new gaskets, sat on the intake manifold. Checking the needle valve for leaks - and the carburetor cover has taken its place. Turn the key. A motor waking up after an operation takes the first steps.
And then … Stop, car! A body piled on trembling legs slowly slides along the wall - I did not expect the worst “reward” for hours of hard work. Having eliminated the trembling of hands, I proceed to the search for "drummer".
Perhaps, because of the defective liners "backlash" of the main bearing? Alternately, I pull off the wires from the candles, excluding the cylinders from work: first, second, third, fourth. Everything is in vain, the "snitch" continues to hammer the engine from the inside.
I listen to the motor with a wooden stick, applying it with one end to the ear, and the other to the block and engine head. Luck! The scoundrel is hiding in the third cylinder. I remove the pan and, turning the crankshaft, pull the connecting rod. There is no backlash!
Is there really a problem with the valve actuator? I unscrew the lid and, having screwed the adjustment screws to failure, I eliminate the gaps. Now the valve mechanism has lost its voice. I unscrew the candles and close the central wire of the coil to ground. I crank the engine with a starter. Knocking !!!
In the hearts I take off the “head” from the motor. What is it? The bottom of the third piston is dotted with small round craters that only a ball could leave … a carburetor shutoff valve. Is he really?
