replacement plugs are not available, proceed as follows:
a. Degrease firing end of spark plug using ELECTRI-
CAL CONTACT CLEANER. Dry plug with com-
pressed air.

spark plug with sharp edges on its electrodes
requires 25-40% less firing voltage than one with
rounded edges.

spark plugs (Part No. 27671-01K).

should be 0.035 in. (0.9 mm).

24 Nm).
