He's clearly knowledgeable and does an excellent job diagnosing and solving the problems. But in order to make his videos better.He really needs to clean the machine off so that you can see what He is doing and also he needs to show what is that instead of simply showing you the result. So he can go from producing an average video to an excellent video with just a few changes. Anyway thanks for the video and the explanations along with the excellent diagnosis.
Oh my gosh, it runs and runs well! I could never do that. Even though I do understand motors pretty well from an old lady standpoint, that was too intricate for me. Great job!
Yep been there,done that. I got involved with Briggs and Stratton engines and the Johnson Iron Horse engines back in the 70s. What you just did my friend, brought a whole lot of memories back. 👍
For me so far the best video out there on this period I have the exact same engine on a trash picked mower I'm going down the rabbit hole with. Especially helpful were the quick checks on piston Where valve seating and thermostatic choke mechanism. Also much appreciated the no intro or acting BS so tiresome on other videos. Plus how crusty that unit was and you just got after it without a lot of fool and around. Many thanks. Yes for me that valve Spring compression tool is a bit pricey but there are no alternatives that I can find. Also for me I think I would follow a star pattern in taking off the head bolts. Again many thanks good job.
I've found those often get the decompression device on the camshaft, stuck in either position, usually from lack of oil changes, but it will cause the exhaust valve to not close completely. I always make sure I buy a Briggs and Stratton engine with the cast iron bore, "IC" has that, or you might as well throw them out as soon as the rings and cylinder are worn.
I've got two self-propelled mowers one 190cc Toro an one 140cc Murray both have Briggs & Straight engines and the pull rope is stiff as a board I've broken the small white pieces that turn the fly wheel on one twice and the other one I didn't put so hard but no luck both won't start I've checked the kill cable it seem to be ok ... there a Easy Start my ace..
You ran them low on oil until they seized. Fill them with oil, remove the spark plug wire, use a rope to hold the band brake, and get underneath and rotate the blade back and forth. You might be able to get them running, but they may knock and burn oil.
I noticed the air vane was looped inside of the auto choke thermostat. (triangle). The leading edge of the thermostat should touch the air vane on the outside. Thanks for the video.
gr8 vid, I have a 190cc briggs flat head I believe has a similar issue with valves, when its hot it looses compression. I am thinking the exhaust valve needs adjustment
I have the same model and did the same job this afternoon. Lower head bolts were not fully tight and the oily residue told me the gasket was toast. Valves were ok, though. The heads are cast so rough it makes sense to spend five minutes lapping the gasket surface flat with a sheet of 80grit sandpaper on a glass or cast iron table. Gaskets hold up much longer between two flat planes.
Not exactly sure of exact spec, but google should give you a starting point. Not sure if Briggs website has a search option for clearances. Thanks for watching
B and S has really gone down hill over the years in quality. Neighbors 1 year old mower is sitting in my barn right now not running. Everything is plastic and junk POS.
They have them listed on Amazon. Small engine compression tester. Mine is a old snap-on tools tester someone gave me. I looked on Amazon and they are reasonably priced. Good Luck!

I.had the same thoughts doesn't show how to.more like what only
That’s where he lost me. Skipped over showing some important details. I don’t like shorts.🤷♀️

should have shown how to adjust those valves, even though they may not have needed adjusting.

I use a drill and spin it backward to get a reliable reading. otherwise the compression release kicks in
Thanks for the tip. Never would have thought of that

Thanks for sharing
Hammer and shock exhaust bolts helps
Where can i buy the valve compression tools? Can you put the link where i can order this tools plz...and thx for the vids.
search Amazon for a Briggs & Stratton 19063 Valve Spring Compressor
It’s smart to retorque head bolts every year
I remove the handle and stand it on its end, make it easier 😊
The exhaust valve is AllWAYS smaller than intake valve 😊😊
Great video thanks
What is the metallic sound when it first starts and when you shut it off?
Not sure maybe a loose baffle. He has hit a lot with it. Crankshaft appeared straight. Not really sure what it was
I bet the crankshaft is bent, too
I did check it, and surprisingly, it wasn't bent
Does anyone know the proper valve clearances on these Briggs Quantam. Can’t find a definite answer on this. Thanks!
Not exactly sure of exact spec, but google should give you a starting point. Not sure if Briggs website has a search option for clearances. Thanks for watching
I set them at 4 thousand
SOUNDS LIKE YOU STILL HAVE TROUBLE COMING WITH THE NOISE WHEN YOU SHUT DOWN-BENT BLADE OR CRANK?
Mower is long gone, but the blade tips appeared to be even. The mower had a tough life. Could have been a possibility.
B and S has really gone down hill over the years in quality. Neighbors 1 year old mower is sitting in my barn right now not running. Everything is plastic and junk POS.
Agreed. Not what they used to be for sure.
what is the torque specification on those head bolts?
See if this chart helps with your specific model engine. Thanks for watching

What type of compression tester would I need to test my lawnmower ?
They have them listed on Amazon. Small engine compression tester. Mine is a old snap-on tools tester someone gave me. I looked on Amazon and they are reasonably priced. Good Luck!
Harbor freight is another one and they have lifetime warranty
Get a HF one for easy warranty
Where is the fly wheel key located ?
Between the flywheel and crank shaft
Missed showing too many critical points. Just for the gist of it…okay video.
