Briggs & Stratton - Not Starting

[lawnguyz]

Hi,
My Briggs and Stratton (model 111P02-0007-F1) lawn mower does not start anymore.

It was working last Friday while I was mowing the backyard. Outside temperature was at 101 degrees F. The lawn mower stopped and would not start. I had to wait for around 10 mins or so then it would start running again. This happened 2 more times.

The last time it stopped last Friday, it never started again.

I checked everything including:
1. float bowl -> no dirt or water
2. I added gas stabilizer and fill the tank
3. I changed the air filter
4. I changed oil

Still it does not start. I wanted to check here for help before taking it to lawn service repair store.

I have recorded a video showing the sound my lawn mower is making when pull the start coil.

Please let me know if you have any ideas on what's going on.

Thanks!

similar to this maybe?

engine makes clicking noise when trying to start - valves not opening

I have a Toro 22" recycler, bought in 2017, and have changed oil and uses stabilized fuel over the recent years. Engine is Briggs and Stratton 128M02-0017-F1. I tried to start it up this spring, and the engine didn't turn over after a few pulls, and then all of a sudden it started making this...

Might be similar but not really know for sure

My lawn mower seems to back fire telling me that valve is not open/close correct?

Next time you get it running and it quits, check for spark. With the temps these days I’ve seen a few bad coils which are either hot shorting or having a hot open which means no spark. If it doesn’t stark now you may have one of these conditions and will not reset it self. Either way if you find no spark, time to replace the coil.

This is an overhead valve engine so please check the valve lash

We did see sparks when we took the spark plug and and touching it against the engine as my friend pulled to start it.

do I have to open the engine to check the valve lash?

Remove the blower housing then remove the cover at the front that has OHV stamped into it
lots of videos showing how to adjust the valve lash and the only catch is remembering a 4 stroke does 2 full revolutions so you need to make sure the engine is in the right TDC when you adjust the valves
While the blower housing os off, get an inspection mirror & check the under side of that tube that goes across the engine
If you decide to take it off for a proper inspection then take plenty of photos so you know how & where all the bits go back together .

a easier method i use for adjusting valves is the OVOOVC method.
One
Valve
Open
One
Valve
Closed
you adjust the valve that is closed. so if the intake spring is depressed, your adjust the exhaust valve, etc.
