Repaired my Riding Mower Saving Big Bucks
Went outside this morning to start my riding mower and move some wood I have loaded up in a trailer. My mower was locked up and would not turn over and start. Evidently, gas can leak from the tank, into the carburetor, then into the piston cylinders creating a condition called Hydro Lock.
I watched a few YouTube videos on how to treat this condition. I'm not a mechanic, but it took me only about 10 minutes to pull out the spark plug, drain the cylinders, and put everything back together again. On my engine, the fuel did not get into the oil reservoir, so I did not have drain and change out the oil and filter. Anyways, after I got the spark plug back in, the mower started up and ran fine - after it blew out a little smoke for a few seconds. Very nice!
All it cost me was about half an hour or so watching various YouTube videos on how to fix my problem. I ate breakfast while watching the videos, so no real time lost there, either. It was a simple repair job, even for me with very little mechanical repair background.

I should also mention that our local Fleet store, where I bought the lawn mower, is down to one mechanic and it would take a number of weeks before he would be able to service my mower. So, not only did I save lots of money by using YouTube to learn how to repair my mower, but I probably saved a good 3 or 4 weeks of shop time as it would have sat there until their one, and only, mechanic could look at it.

Of course, I took the opportunity to gently complain to the Fleet store about their lack of mechanics. Normally, they would have 3 or 4 full time mechanics in the shop, as in the 30+ years in the past. It's our main lawn mower sales and repair shop in my town. So, not having mechanics in the shop is a real problem.
As old as I am, I am really thankful for all those YouTube videos on home repairs, gardening, raising chickens, etc... Probably saved me a $150 repair bill on the mower and 3 weeks or more time sitting in the shop. And it felt good to do the repair myself.
