Since air gap between center and side electrodes of
the spark plug increases gradually during normal
operation of the engine, check condition of elecĆ
trodes after every 25 operating hours. RecomĆ
mended air gap is 0.030 of an inch (0.762 mm). CorĆ
rect spark plug to use is: Champion RJ Ć19LM.
/3& The spark plug usually lasts a long time; howĆ
ever, the plug should be removed and checked
whenever the engine malfunctions.
