Hi 25mal, The spark plugs are located below the coil in a hollow tube in the head. You must remove the spark coil retaining screw to access the removal of the spark coil. This will expose the spark plug at the bottom of the hollow tube in the head. The spark coil is about 6-7 inches long. Once removed you will see the spark plug at the bottom of that tube. There is no typical spark plug wire attached to the coil. Find the top of the spark coil (about 1-3/4-2" in diameter). There's a single small metric bolt holding the spark coil in place. It will not come out until that screw is removed. Good luck!

Ignition coil is the correct term, the removal process is very easy after removing a screw the holds the coil you then simply pull the coil up from its seat, then you will see the spark plug... use a flash light to get a good view, removing the plug is tideus .. you must be sure not to get any debris inside the spark plug chamber.. when you replace the plug use anti seize grease & dielectric grease inside the coil to the plug
