1972 shovel what type of spark plug can i use other than harley and what is the gap
Best to use Harley plugs
If the plugs require cleaning between tune-ups, proceed by degreasing the firing end of spark plug using ELECTRICAL CONTACT CLEANER and then dry plug with compressed air. THEN using a thin file flatten the spark plug electrodes because a spark plug with sharp edges on its electrodes requires 25-40% less firing voltage than one with rounded edges. If the plugs cannot be cleaned, replace with them with 6R12 spark plugs. Check the electrode gap with a wire-type feeler gauge and bend the outside of the electrode so only a slight drag on the gauge is felt when passing it between the electrodes. Proper gap measurement is 0.038-0.043 in. (0.97-1.09 mm). Check the condition of the cylinder head and plug threads and if necessary remove deposits by applying penetrating oil and clean them out with a thread chaser. Apply a good sensor safe ANTI-SEIZE to the plugs and then install and tighten them to 12-18 ft-lbs (16.3-24.4 Nm).
