I know this is going to sound elementary to most of the people here in this forum, but I'm stuck and am going to ask anyways.
I'm trying to replace the spark plug wires on my mach 1. Someone told me I have to screw them out. I've tried this, but not too hard. I don't want to damage anything in case I was given bad information. Is this houw you do it, unscrew them?
Any help would be greatly appreciated. Below is a shot I took of my setup. It's a little crowded, but I drew a red line on the sprark plug wire.

Correct, just unscrew the wire.
It might be better if your able to remove the coil, unscrew wires then screw in the new wires.
