Hey Guys,
Have a question about spark plugs. I notice that there seem to be two kinds, ones with screw tops, and others with plug tops. Is there a difference in connecting the two? I pulled a plug wire off my bike tonight out of curiosity without turning it and it came off, but I noticed there was a screw top on the plug, which makes me think that the spark plug is wrong for the wire, or the wire connector is stripped (I didn't use too much force when removing the wire).
PS, never owned a gas motor before, bicycles don't have spark plugs.
