Under the condition that the environment is extremely dirty, please increase your maintenance frequency. If dirt and dust are absorbed into the engine, the rapid abrasion of engine will occur. So please don't use the engine without air filter. The maintenance procedures are listed below.

The engine is completely electronic controlled, so there is no need to adjust the distributor. The electronic igniter is composed of electronic components, so don't heat it intentionally, and you shouldn't pull out the ignition wire unless you need to change parts.
