How are you testing for spark? The part that bolts next to flywheel is the module, the parts that bolts over the spark plug is the coil/transformer. You replaced both? Stop switch wire disconnected? On my 360, it ended up being the wiring (from module to transformer). It must have had very small cracks in the insulation and current must have been going to ground. I too replaced both and still no spark. I just used shrink wrap tubing and electrical tape on the original wire. After I got it running, as a test, I put the original module and transformer back it, it still ran
I have a spark tester I made up. It worked great for testing spark on my 450. I will check the wire , I guess that"s all that's ledt to check . Did disconnect on /off switch also tested it with a meter. Thanks for your help. My other 360 runs fine.

These saws are a royal pain in the a$$ when it comes to testing for spark. I do what Supercharged86 suggested and use known good components. From what you are describing, it sounds like you have already replaced everything but the coil...they are what tends to go bad most often on these ignition systems.
