Spark Plug Service
Spark plug type: F6RTC/F6TC/F7RTC/F7TC
For normal engine operation, ensure the spark plug gap is correct
and check for carbon deposit around the spark plug.
1. Remove the spark plug cap.
2. Clear away dirt around the spark plug base.
3. Dismantle the spark plug with a spark plug wrench.
4. Visually check the spark plug. Clean with a steel brush. If the
insulator is damaged, replace the spark plug.
5. Measure the spark plug clearance with a spark plug gap
gauge. The clearance should be 0.7-0.8 mm. If adjustment is
necessary, bend the side electrode carefully.
6. Check if the spark plug gasket is in good condition. To
prevent cross threading, screw in by hand.
7. Screw in the spark plug to the bottom first by hand and then
screw in by a spark plug wrench and compress the gasket.
7a. If a new spark plug is used, twist another 1/2 turn after
compressing the gasket.
7b. If reinstalling a used spark plug, only twist another
1/8-1/4 turn.
Don't touch the muffler when the engine is running or hot.
The spark plug must be tightened securely, or it may become
very hot and damage the engine.
Spark Arrester Screen Service
If the engine muffler is equipped with a spark arrester screen,
remove and clean it according to the service intervals.

hardware.

6. Remove the spark plug. Place about a spoon of fresh engine
oil into the cylinder. Crank the engine to distribute engine oil
evenly.

area where gas fumes could reach an open flame or spark, or
where ignition sources are present (space heaters, hot water
heaters, furnaces, etc.)
10. Loosen the oil drain bolt and completely drain the gasoline
out of the carburetor into a proper container and screw the
oil drain bolt down. Remove the sediment bowl after closing
