Busi is fast die fast because once dirty electrodes by crust . If these types of 4 stroke engine ( Honda ) then the cause initially because oil burned. But the type of 2-stroke engines because the fuel mixture into the oil too much . Usually dirty spark plug electrode by the former residual oil combustion .
The cause is due to a mixture of other gases too fat so that unburned fuel will remain in the combustion chamber and form soot fouled spark plug electrodes . To ascertain the cause observe electrode spark plugs .
If the white insulator yellow . Electrodes on fire . Cause thin mixture , when the ignition is too early or too low quality gasoline .
If the electrode and insulator sooty . The cause is too much gas mixture ( too rich ) .
If the electrode and insulator brown and very dirty . Means the oil burned.
