Replacing and cleaning the spark plug
(Only use F6RTC (Nanjing Huade NHSPLD) with engine DY1P64F)
After the engine has cooled down, remove the spark plug with the provided socket
wrench.
Clean the spark plug with a wire brush.
Use a setting gauge (adjustment gauge), and adjust the electrode gap to 0.75 mm.
Insert the spark plug carefully by hand, in order to avoid any wrong installation (not
properly aligned to thread).
After the spark plug has been tightened manually, use a wrench to tighten the spark plug
tightly to its washer.
