I am still having spark plug issues and I may be using the wrong plug. Currently I am using Champion RC12YC. This is on a Vanguard 18 hp, model: 356447, type: 0142-E1
Should I be using the Champion QC12YC or RC14YC or other? The owners manual states the gap needs to be at .76 mm or 0.030. Hopefully, I am just using the wrong plug and can get this engine running smoothly again. Thanks!
