There are several everyday phenomena that are easy to cause anxiety for beginners playing custom RC cars

There are several everyday phenomena that are easy to cause anxiety for beginners playing custom RC cars:

1. When the engine is running, there is an intermittent sound of metal collision: ignore it. This is generally the sound of clutches and gears

2. The engine will die as soon as it is refueled: generally, the auxiliary oil needle is too rich in oil. Just take a bit of auxiliary oil needle.

3. After idling for a few minutes, the fire will die at the touch of touch: it is normal because the oil discharge is not smooth at idling speed as long as the accelerator slowly increases. The accumulated oil in the engine is sprayed out at high speed.

4. When the oil is collected, the engine speed does not come down, as if singing and shouting: See if the oil is poor?

5. The fire will die as soon as the brake is applied: Please confirm whether the damper maintains a clearance of about 1MM when the brake is applied. If the throttle is closed, it will stall, if the throttle is too large, the clutch has been engaged, the brakes are equivalent to hard stopping the engine, and of course, the engine will stall.

6. The engine should not be touched when it is hot: the engine should not be touched when it is hot.

7. Can't start at all: Does your igniter have electricity? - Unscrew the burner and connect the igniter. The burner should be very bright. If it is not bright enough, charge it!

Did the oil get into the carburetor? - Check if the oil has reached the carburetor in the fuel tank? If not, plug the exhaust pipe and start it up when you start it.

Are you sure that the oil is not too wet for the fire head? ——Remove the burner and idly pull the engine a few times (idling a few times for electric start). You can spray excess fuel to avoid excessive fuel flooding the burner.

Does the electric starter have enough power? Is the hand pulling method correct? ——If the startup speed is not enough, or the hand pulling method is wrong, it will also cause trouble.

8. The engine is very tight and can't turn: Generally, there is too much oil in the engine. Remove the burner and pull it several times to drain the accumulated oil. Please don't force it! ! Otherwise, it will damage the hand-pull/electric starter and even cause damage to the engine (such as damage to the rear cover, damage to the rear cover teeth, damage to the one-way bearing, etc., and even the worst we have seen hard to break the connecting rod and crankshaft). !).

If it is still tight after draining the accumulated oil (usually, new engines will do this), you can loosen the burner a little and let the engine leak a little bit so that it will not be so tight, so that starting the engine will not cause damage to other components: )
