Won't start, no spark on the bolens sl150 weed eater

SOURCE: String-trimmer (weed eater) won't start.

the only thing left is the coil that is inside the cover right next to the flywheel with a gap of 10 thousand of a inch a business card will work but a new coil is almost thr price of a new trimmer unless you have a used one

Testimonial: "Thanks for the help. We did look at the coil. Got about 30 volts out of it when we pulled the starter. I hope that means it's OK."
