Spent days chasing a miss firing briggs 13hp engine. 21B807. 0290 E1. 0512227A. For those in the know. I have given myself the label of "parts replacer" not mechanic, also for those knowing. Or not knowing as is my case.
Only to ponder, was it just the fuel solenoid not operating correctly after I had "Dr" the plug by removing the plastic and attaching the terminals to the solenoid prongs.
Long story, I replaced the entire engine with a "donor", then had the same issue, only to have it resolved easily by swapping out the bad solenoid for a good one.
I have embarrassed myself with the amount of time and money wasted chasing a miss fire or engine pop. Even employing AI to affirm what I was doing was the correct method. To any wondering if AI helps, well, in my case it confirmed just what an imbesile I am when dealing with things mechanical. I hope this helps someone who thinks they know the one solution in a thousand problems, when in actual fact it's one simple problem amongst a thousand solutions.
 
Very very very few techs on this site put any value in AI postings. We rely on PI, “PROFESSIONAL INTELLIGENCE”

Thank you for the advice

Artificial intelligence gives a list of causes, for example, of what can be the problem, along with some solutions. It is not a comprehensive list, nor always specific. That is where common sense, experience, understanding basics, and troubleshooting come in on the human side.
 
I wish it was that simple for the engine I finally had to give up on. It was randomly backfiring out of the carb. I mean it would shot a flame out of the carb. The only thing I didn't do was go inside the crankcase. About the only thing I didn't change was the cam.

It could be I was over thinking 🤔
 
What's to overthink? The machine was not running properly, and you took the WAG method. "Been there many times".

In reality, the anti-backfire solenoids get gummed up from fuel additives and many end up stuck with rust due to Ethanol fuel collecting moisture in the fuel tank.

The first thing to verify if a fuel solenoid is working is to listen for a faint click when the ignition key is turned on just before going to the engine crank position.

Anyone on this site with years of small engine experience has had their share of costly guesses and mistakes filed under the category of "practical experience". Most of us over 50 years old grew up in a time when the internet did not exist, just the willpower to deal a problem as a challenge and then resolve the problem.

AI has no such practical experience because it is not human. All AI does is list a bunch of random information and often guesses from data gathered off the internet from random blogs and written communications.
