Replacing Spark Plugs

Replace spark plugs after every 400 operating hours to
assure proper engine performance and reduce exhaust
emission level.
Correct spark plug to use is a Champion RC 14YC or
NGK BPR 4ES.
Recommended air gap is .032".
Note: The spark plug usually lasts a long time; however,
the plug should be removed and checked whenever the
engine malfunctions.
1. Clean area around spark plugs so foreign matter cannot
fall into cylinder when spark plug is removed.
2. Pull spark plug wires off spark plugs and remove plugs
from cylinder head.
3. Check condition of side electrode, center electrode, and
center electrode insulator to assure there is no damage.

Important
A cracked, fouled, dirty or otherwise
malfunctioning spark plug must be replaced. Do not
sand blast, scrape, or clean electrodes by using a wire
brush because grit may eventually release from the plug
and fall into the cylinder. The result is usually a
damaged engine.
