Precise and to the point. I've seen way to many of these mowers that are basically a toss away once they won't run any longer. Although, the plastic carb won't rust.
Thanks you. Very straight forward. I've got a problem with the oil spitting out on the deck. Now I've got some ideas how to track the problem down. Appreciate the info.
Thanks 👍 I broke my camera and had some major sound problems. I was able to correct them in Imovie, but when put on UA-cam the sound was fuzzy. New camera back up and running. Still busy having a hard time keeping up. Take care Bruce. Thanks for commenting and watching. Bob
Thanks! I was asked to look at a toro 22” similar to that one. I figured I would at least start by draining the oil and replacing the spark plug and filter. After doing that, it was still spitting oil, so I searched and found your video, which almost confirms that all hope is lost for this puppy. :( Thanks for the education!
another thing that happens is the head gasket is bad. or your valves not seating. for the 65 compression Briggs has a valve release so 65 can be good still 80 is better but if the head gasket is leaking then the compression would be lower. a good way to tell if it is a head gasket leak into the valves is run it shut it off and pull your dipstick if smoke comes out then you know exhaust is getting in from a blown head gasket.
Thanks Mick, I have been struggling with some camera sound issues for the past month or so, Finally got a pro camera hopefully it does not get dropped or knocked over for at least 6 months or so....
Hey buddy do you know why a mower would spit oil out of the of the black tube under and behind the carbrator. Leaking on the frame and deck and front tire. Leaking bad. SO I FOUND OUT BY TEARING INTO THE ENGINE AFTER I REPLACED THE BEATHER ASSEMBLY AND IT WAS STILL SPRAYING OIL OUT OF THE BREATHER ASSEMBLY, I FOUND OUT THE HEAD GASKET WAS BAD. HAD A SMALL PART MISSING CAUSING CYLIDER PRESSURE TO GO INTO THE CRANKCASE.
have an625ex brigs ohv been having oil coming out of breather in carb. cleaned plastic carb. replaced reed valve under crank. still having oil coming out of top breather port , took head gasket off looked ok .. thanks for helpful tips i got more testing to do .
I don't think so, because there is not oil pushing out the breather, no smoke in the dipstick, but I can check. The engine was way overfilled with oil when I got it as well.
Yes much more likely that the head gasket would fail before an issue with ring/cylinder...the air will get down into the crankcase if gasket fails between cylinder and pushrod gallery which is where they always fail on briggs... I had an engine spitting oil and smoking simply because the wrong oil was put in...turns out the lady put 2 cycle oil in the crankcase...that low viscosity was making its way right past the rings into the cylinder and burning off and then spitting out the exhaust because not all of it was getting burnt...it was flooding the cylinder with oil...
I tipped my Troy Built TB110 carburetor side up to replace the blade. Now im having problems with the plug turning black, clean it, it runs again. No leaking on onto the deck, When I took off the air filter plate and looked at the back side i noticed oil in the pattern of the carburetor gasket as if the gasket is bad. Probably the original gasket. I done a complete tear down rebuilding the carburetor cleaning the jets, fuel bowl, washing all plastic parts and flushing them with carburetor cleaner. Fuel tank washed flushed and dried in the hot sun. No oil on the air filter. Only a little bit on the air filter plate on the top hole. Is it normal for a little oil to be on the top exhaust plate and hose that pushes in. The main problem is that the mower will fire over and start and cut grass it'll run great sometimes stalling out due to black spark plug. I clean the plug and it fires right back up. I'm wondering did i get oil into the carburetor when I tipped it on the side to change the blade. Im also wondering if I need a new carburetor gasket due to seeing the pattern of the gasket in oil. Thanks for any advice that you can help me with.
I have the same one. I have oil spitting out of the muffler I think. What is that silver piece in the front left? According to my manual, it's saying it's the muffler. It's spewing oil out of that hole and blowing white smoke. I know what you're gonna say.... Yes, I did do a tune-up... I changed the filter and spark plug and also changed the oil. I don't know anything about doing a compression check. I may have to take it into an authorized dealer.
i,d have a good look at the piston rings mate and maybe the cylinder block walls just to confirm it etc unless you have done it off camera still a good video mate cheers from Australia to your area.
I’ve been recording the compression of all 4 strokes coming into my shop the last month or so to get an average baseline. Briggs, Tecumseh, and Koehler. They all have ranged between 55-65 psi with one coming in at 85. Thing is, they all passed and operated fine. In your vid when you did yours I was surprised when you said it was low, then even MORE surprised when it failed the check. I’m doing this only about 18 months so I’m learning. Is there a reason why my checks are coming in “low” but still seem to pass? Thank you, and please keep up the great work. I love your vids my man.
Not familiar with the newer models, but am thinking they have compression relief systems that can fool us into thinking compression is low. This oil complaint seems to be somewhat common on this style engine, perhaps the head gasket is blown allowing oil from the crankcase to sneak into the combustion chamber through the valve/push rod chamber.... Can't imagine this engine being all worn out, seems kinda new, unless someone ran it low on oil. I hope to get to mess with one of these things someday
Air coming back up through the dipstick tube could be a ring problem or cylinder scoring like you said but it could also be a head gasket...if the head gasket fails internally (between the cylinder and the pushrod gallery) then air will make its way into the crankcase and out the dipstick tube...this is where the briggs and stratton head gaskets are known to fail
I am still getting used to it, but it really helps with the tractors. I watched your review and ordered from the same place. I just wish the ramps stayed better attached in the up position.
That compression gauge is for cars not mowers. Also most mower engines have compression releases to make starting easier. Makes for lowered pressure values.
I have a question. you pulled down the cover for the air cleaner and there is a small plastic tube that runs off the full tank at the top. why would gas spill out of it when the tank is full when moving the mower. it starts to leak out of the air filter housing on to the mower deck under the air filter ?any one know ?
I've had mine for about 2 years now, just lost the warranty, and I could say that it's the biggest junk ever. I don't think I've used this thing 10 times. Not cheap either.
That was a disappointment double wide, you don't throw out an engine just because it's a bit worn or has a broken ring. You rebuild it, you can can put a set of rings in can't you?

Nice job finding the leak, hope you will dismantle the engine to see what was wrong, rings, piston, scored cyl. wall, etc.
We shall see

My mower will spray a little oil out the muffler and it shoots some gas out the breather.but it been doing this for 2 years mower runs great any idea
Loving the lift table brother
Not as much as me. Put it on your wishlist, I can see it on the outside of your shed.
@@doublewide6 lol do I have a wish list.. I don't like to talk about it lol
I rebuild briggs engines and that one is 1hr labor piston rings gaskets and piston arm is less than 100 bucks. So it's worth fixing.
Great video! Very useful. Thanks
Glad it was helpful!
Great video Bob. Sad that engine is not good those a pretty good mowers. I like your pneumatic work table!
Thanks 👍 The table is new and I am really putting it to use lately.

Very informative. Nice lift ya got there too!
Yeah a really good video with lots of top tips.. just what I would expect from a professional
Thanks Mick, I have been struggling with some camera sound issues for the past month or so, Finally got a pro camera hopefully it does not get dropped or knocked over for at least 6 months or so....
@@doublewide6 yeah I did notice some differences in sound. If it's not the mowers is always something else lol
That tester sure saves a lot of time 👍
I would love to see the tear down to confirm the leak down test. Great video
Great suggestion!

Great vid. I have been subscribed for awhile now. Cheers!
Awesome, thank you!
have an625ex brigs ohv been having oil coming out of breather in carb. cleaned plastic carb. replaced reed valve under crank. still having oil coming out of top breather port , took head gasket off looked ok .. thanks for helpful tips i got more testing to do .
Likely a blown head gasket between the cylinder and pushrod gallery
That was my thought also.
That’s what I was thinking. DW6! We can’t stand the suspense, pop that head off! Haha
I don't think so, because there is not oil pushing out the breather, no smoke in the dipstick, but I can check. The engine was way overfilled with oil when I got it as well.

@@macknumber9how do u fix ablown head gasket?
Extremely informative video. Great tips and instruction. Thanks for the video.
Glad it was helpful!
Nice job DW6, great lift table, wish I had the room for something like that. Thanks for the vid, 👍👍
Thanks 👍 It takes up a fair amount of space, but it is an everyday tool for me, so it is worth it.
Another cause for oil shooting out the exhaust is over filled with oil.
It was overfilled by about half a quart when I got it. I missed that one in the video thanks.
Bob cant a blown head gasket cause air to go into the crankcase? Ive seen this on a lot of the push rod OHV Briggs before. Thanks Sir.
thanks for your video answered a question i was looking for

Did you just get that lift? That's nice.
The lift is new, I like it, but it does take up a fair amount of space. Handy lifts SAM version. about $1900. online delivered.
@@doublewide6 where did you get the lift table you had? Can you put a riding mower on that new lift?
I have the same one. I have oil spitting out of the muffler I think. What is that silver piece in the front left? According to my manual, it's saying it's the muffler.

How does a leak in the sump gasket cause oil to squirt out the muffler?
Air coming back up through the dipstick tube could be a ring problem or cylinder scoring like you said but it could also be a head gasket...if the head gasket fails internally (between the cylinder and the pushrod gallery) then air will make its way into the crankcase and out the dipstick tube...this is where the briggs and stratton head gaskets are known to fail
So is that mower just scrap now. Or is it worth doing a ring job? I got that mower.
Could be head gasket leaking in to the valve train in to the crank case
That’s a good looking lift! Are you loving it?
I am still getting used to it, but it really helps with the tractors. I watched your review and ordered from the same place. I just wish the ramps stayed better attached in the up position.
Excellent video! I gave you a 👍🏻 too.
That compression gauge is for cars not mowers. Also most mower engines have compression releases to make starting easier. Makes for lowered pressure values.
Does it have a reef valve???
Very helpful
Glad you think so!
How do you know its not a blown head gasket?
There is no coming out the breather and there is not any smoke coming out the dipstick when hot.
Electric start is good for older folks and weak people
Great video
I use c clamp to hold blade in place for test
Was that one of the new "just check and add, never change the oil" Guess it lived the 3 yrs the manufacturer gave it with no oil changes.
I have a question. you pulled down the cover for the air cleaner and there is a small plastic tube that runs off the full tank at the top. why would gas spill out of it when the tank is full when moving the mower. it starts to leak out of the air filter housing on to the mower deck under the air filter ?any one know ?
Check the carb needle valve seat and float adjustment. Problems with these cause gas to leak out of carb.
@@drcajundan thanks but your answer has nothing to do with my question.
“Bad engine, new air filter. $20 obo”
What PSI would you normally see on this engine during your compression test?
Anywhere from 30-160. If you get at least 90psi, it’s a good amount.
I've had mine for about 2 years now, just lost the warranty, and I could say that it's the biggest junk ever. I don't think I've used this thing 10 times. Not cheap either.
thats a real shame that looks like a nice mower
I agree.
That engine doesn't look that old an it's already junk.
It' a Briggs and Stratton!
Yes, may have run low on oil and seized.
Such a shame the Toro looked in nice shape unfortunately another engine on that mower deck there it looks like.
Super . Thanks. Much appreciated. Kevin June 15, 2024

sure looks good too be so bad , a shame.
I’ll just buy a new mower
