Briggs and Stratton 123K02 No Spark

Hello all,

I had purchased an Briggs and Stratton lawnmower that some guy couldn't start for $40. Assumed it would be an easy enough fix.

Model: 917.378451
Engine: 123K02-0183-E1

I got a kit to rebuild the carb and then replaced the spark plug. Figured that should get it going.

But there seems to still be no spark. I followed some video and checked the resistance on the ignition coil. The old ignition coil showed 'OL' so pretty sure that was no good. I ordered a new one on amazon from HIFROM that looked to have same part number. The new one looked a little different than the old one, but it fit the mounting bolts so I installed that. 


Saw this on the HIFROM amazon page
"4. Please note that: the one we sell is for later 802574, not for the earlier, please check the pictures carefully before you buy it."

Anyways, I tried to start again and still didn't work. No spark still. I disconnected the wiring going to the kill switch and tried to test for spark again, but nothing. The magnetron is spaced at 0.010"

Now a few questions:

1. The flywheel has the two raised areas on opposite ends that wipe past the ignition coil. Are both ends supposed to attract metal? Only one side will pull in metal, the other side does not.

2. Is the only possible problem here the ignition coil, flywheel magnet, or spark plug? That's what I'm figuring, but the ignition coil and spark plug are new.

3. Is the new ignition coil not being the same as the old one the problem? The coil itself seems fine and has a good resistance reading across the coil (dunno, just saw some video saying it should read X Ohms across). 

Thanks
