One thing I noticed about this engine with the bad coil....... It didn't backfire.

Thank you. Also @Auto Doc's @Forest#2 and the others for this imput. That explains what I'm missing. Tester ordered.

True that. But what I'm supposed to be looking at is gaps between sparks, instead of a constant blinking, correct? Even with the junk ones like I have, these gaps are visible. I did notice some gaps in the spark. But they didn't coincide with the backfiring. As in many times there was several...

With the spark testers I have, I see no formidable differences between either side. Note: They're not adjustable air gap spark testers. But I they do show when exactly the voltage comes through. Both sides glow bright.

Here's the video. I'm not touching the throttle. The RPM's went down on their own. A few seconds later, they came back up.

The carb is clean as a whistle. Even the bowl had almost nothing in it. The valves were at about .06. So I didn't mess with them.

Tried your suggestion but, nothing changed. But I have a side question about what happened when I tried this. With the wires disconnected from the coils, then turning the key off, 3 seconds later, the engine dies on it's own. Reconnected the coil wires, then turn the key off, it dies right...

Oh lord. I hope not.

407777 0188 B1 On a service call, started out, this thing ran like crap. Lot's of back firing through the exhaust. After about 10 minutes of it running & mowing, it seemed to clear up. It was still backfiring, but in spurts, it would completely clear up for several seconds. Maybe even a...

I sure miss my old parts girl at O'Reilly's. She came from Car Quest from back in the 90's. Sharp as a tack with parts & part numbers. I told her (jokingly) back then I wanted to marry her. And it's been a running joke for about 30yrs now.

After I confirmed that the pulley I needed was a V pulley, it clicked as to why there was no B dimension. IMO, the parts person should've known this.

On my own mower, I have a file that I keep that sort of info in. Including an updated list on the parts I've replaced. I used to do that with all my customers. It was tedious. But well worth it when they came back for repairs or warrantee's.

Nailed it.

They should know how to look up their own parts better than us.

I always joke with the kids at the automotive parts stores when they start asking all those questions about the vehicle I'm ordering parts for. When I've given them everything, I always throw in "And the antennae is on the right." What was confusing was that this used to be a V pulley. Without...
