The lawn mower that won't start!

Hello all, dear hivers!

A few days ago I got a call from my "fix it all" friend who had a lawn mower that wasn't working, and he asked me:

Mike do you want to get your hands dirty for a couple of hours?

In response I told him yes (hahahahaha).

Said, done I found myself with him in his garden and this mower that didn't want to be running.

We did a series of tests, first with the starter function on,
but the spark plug would get wet so it wouldn't start.

Disassembled the air filter to see if the fact that it was very dirty was to blame, but nothing, even then it didn't want to start.

Testing went on for about an hour more until we got to a good point: we were able to start it but only with the starter function.

At that point my friend immediately got the flash of genius: if with the start function it runs, it means that the amount of gasoline coming in doesn't have the right (stoichiometric) ratio with the air.

All this means is that the carburetor is dirty and the sprayer is clogged: no harm done, disassemble, clean and reassemble!

Come on Mike, with your help we'll get it done in the blink of an eye!

I didn't even have time to tell him yes, that he already had the tools in hand that he was unscrewing the intake box and untying the carburetor from the cylinder head!

After only 5 minutes, the poor mower was on the "operating table" with already an organ removed!

Look at him, poor guy!

Taking over the carburetor, he emptied the bowl into a canister to recover the gasoline, and gave me a pair of gloves, a brush, and some gasoline to wash it all down!

Of course, I proceeded with his total supervision, and he perfectly explained all the locations where to clean insistently in order to remove impurities.

I unscrewed the sprayer (it's housed in the middle part in the middle of the float).

The float is used to shut off the fuel supply when the tank is full; kind of like the toilet bowl, when it's full the float shuts off the faucet!

I cleaned everything thoroughly, as you can see from the photos.

As you can see I also reassembled the pan!

Once cleaned, I gave it back to my friend who in no time reconnected everything: the gasoline delivery, the oil vapor recovery hose (he told me that these vapors that are created are called Blow-By, meaning that some of the combustion pressure in the combustion chamber also transfers to the oil pan) and all the linkages for the engine to run properly.

Well, now for the litmus test!

Broooom, it started!!!

Once again, my friend made me discover something new: I'll trade it for a chemistry pill, since he's always asking me for something, kind of like the drawings I did in elementary school! (ahahahahah).
