Check the spark plug andcylinder when conducting, with Central High voltage line touching the spark plug Terminal, and then turn on the ignition switch, high pressure electro-hop position. Jump position in spark plug gap, then the spark plug is good, otherwise, it is to berenewed.
4, Spark plug electrode gap adjustment: spark plug gap has differences in variousmodels, generally should be 0. 7-0. 9, check the clearance, spark plug gauges or thin pieces of metal that are available. If the clearance is too large, screwdriver handle to tap external electrode, its normal clearance; clearance is too small, you canuse screwdrivers or metal plates inserted electrodes flipping outward.
