Setup, Compatibility & Care
To install this spark plug cap, first ensure the engine is completely cool. Carefully pull the existing cap off the spark plug and unscrew it from the high-tension lead wire. Inspect the lead wire for any signs of cracking or fraying; if damaged, trim the wire back to expose fresh copper before installing the new PetrolScooter cap. Screw the new cap onto the lead wire firmly until seated, then press it onto the spark plug until you feel it click into place. To prolong the life of the cap, keep the area around the spark plug clean and free of oil and debris buildup, which can cause electrical arcing.
