The timing of Kato excavator engine ignition is as follows:
After the installation of the distributor, if the octane number selector is determined according to the octane number of the fuel, it is considered that the basic ignition time of the engine has been determined. However, in order to find out the correctness of the centrifugal ignition advance device and the vacuum ignition advance device for the distributor, it is necessary to test the actual driving. The ignition timing angle at rotating speed is usually used by the ignition timing lamp.
1 the clearance of the distributor contact is adjusted in advance.
2 the 2 of the three wires of the ignition timing lamp are connected with the fire line of the battery and the ground wire head respectively, and the other 1 are sandwiched on the high pressure line of the first cylinder. (the connection method is also different because of the different types of lights when the point is fixed.)
3 mark the timing mark on the engine crankshaft pulley or flywheel with the flash of the ignition timing lamp, then the ignition advance angle of the engine can be observed with the naked eye. The method of observation is to observe the timing mark on the crankshaft pulley and the scale between the pointer on the timing gear cover. Advance the ignition when moving in the opposite direction.
4 just after opening the large throttle valve, the timing mark immediately follows the engine rotation direction before the centrifugal ignition advance device works. That means the ignition time is late.
5 the throttle valve is closed, and the ignition time can be advanced in advance under the combined action of the vacuum ignition advance device and the centrifugal ignition advance device.
