Spark issue

I've got an electric start Subaru 9hp EX27 that I'm trying to get going. It had no carb, ignition switch or diode rectifier when I got it. I got a new carb and ignition switch, got those hooked up. I am waiting on the diode rectifier but I wouldn't think that would have anything to do with the engine not starting, that should just be for returning charge to the battery.

Anyway, I accidentally grounded the kill switch wire that goes to the ignition coil to one of the wires coming from the 200W charging coil that should connect to the diode rectifier. It fried the ignition coil. I ordered a new ignition coil and installed it. I'm not getting spark. I had two or three various other plugs laying around so I checked them and one of the smaller plugs showed a weak, intermitten spark. The correct plug shows no spark at all. I've checked the proper gap for the ignition coil. Any ideas or suggestions?

The flywheel magnet has pull? Is the flywheel spinning via starter or hand?

Flywheel is spinning by the starter, good compression, fuel smell on the spark plug when I take it out so it appears to be getting fuel, just no spark. The flywheel magnet appears just as strong as would be expected. I don't know that there is a magnetic "strength" or how you would measue the magnetism, to me it's either magnetic or it's not, but it pulls metal to it as strong as I would expect it to.

Just that the magnet pulls. I know of no test. Is the coil the exact unit called for in the manual, and (hopefully) not chinese . Does the coil look suspicious like a bring back/resale?

Could you of installed the coil upside down?

I'm guessing you mean backward. No, the ignition coil is offset to the left, not top centered like a typical Briggs coil. It is on the correct way.
