"Start with the simple things first" that tells me you know your stuff! Great video - I liked it - I subscribed to your channel. Thank you for this video & God Bless.
Thank you for sharing your wisdom and your easy way of explaining and not making it over complicated. It annoys me to see all of the negative comments critiquing everything you say. Folks if you don't like it don't watch it if you think you have more knowledge and wisdom then you don't need to watch it. Don't critique him. He never asked for your opinion
How am I going to know if I like it if I don't watch it?! When authors post something on you tube, people are going to comment whether the author asked for it or not. And if I was posting something to help the general public, I would WELCOME critiques so I could be sure I'm doing a good job OR make changes if my posts were lacking in some way.
Mine was the carb. Engine was getting flooded on my JD lawn tractor and would smoke like crazy when it started. I removed the spark plug and about a pint of gas poured out of the combustion chamber through the spark plug hole. The crank case was filled to the top with gas and the oil was super diluted. Turns out the carb was getting stuck open and so when it was not running, gas was just filling up the entire engine. I put a new carb on it for $25 off amazon and a fuel shut off valve to make sure it does not happen anymore. Runs fine now.
Good call! I see that often also, but usually the customer complaint is the engine will not start (due to a cylinder being filled with gas). If the engine does start and I see gas shoot out of the muffler I know it's the carb. Sometimes it's just the fuel shut off solenoid stuck open from gunk. Bad part is that many times a nee solenoid alone is nearly as expensive as an entirely new carb with new solenoid included.
Same thing on my old Troy Built Pony. I just put a manual shut of valve on the fuel line. It eventually would not start because I thought the valves come out of adjustment, but wasn’t it, so I just got a bigger amp battery. It finally give up the ghost when the transmission wouldn’t go forward😞 this only took about 1 and a half years… mind the deck kept throwing belts off too🤬

On the topic of the fuel pump failure.. I heard someone else say the underlying cause for the fuel pump issue is a failing head gasket that over pressurizes the fuel pump damaging the diaphragm
Just happened to me. Major Kiss concert in my backyard. I had just added oil thinking it was low. Not a clear oil line in dip stick. Kind of streaky and not a definite line. Will drain some and try again. Thanks for the thought.
Check this video out as well. th-cam.com/video/RMEMASwF7dk/w-d-xo.html. Your fuel pump could be letting gasoline into the engine oil and overfilling the crankcase. That also might be why your oil line was hard to read (mixed with gas), and also, it might be why it started smoking.
New subscriber….I’m dealing with a smoking Husqvarna 775ex and I’m thinking too much oil but, no drain plug. So I’m working on a method to remove some oil without turning it on its side…which probably would not hurt it. But your video helped me confirm my thoughts and eliminate other possible failures. I’ll check out your other stuff. 👍🏻
Thank you for the video. My Ariens riding lawnmower is now running great, because of your video. I thought I was going to have to replace it. So, Thanks again.
Hi, mine is still smoking, white smoke. It's a poulan pp19a42 with a briggs 19 hp. Oil level is okay. Changed spark plug, fuel filter, oil filter, and air filter. I will check the compression next. What should it generally be? Nice video
Was the oil level too high before you changed the oil? It could be a head gasket, or valve seal leaking. Even after it's fixed there will be some oil in the muffler so it will smoke as it burns off that oil residue in the muffler.
@@Mechanical_Mind turned out to be the head gasket. I replaced it and the valve cover gasket. Checked the valves also. Started right up and not a single puff of smoke.
Got a mower from a friend. Ran great last year. This year he serviced it and got the black smoke with oil blowing out of the muffler. Checked, overfilled with gas in the oil. So... bad fuel pump, head gasket?? What?? Oil at the carb from manifold? Would vary much like a direction to go.
I've seen that mostly happen due to a bad fuel pump. (Often caused by using gas that has ethonal in it. Use ethonal free gas if you can) I'd check the fuel shut off solenoid on the bottom of the carb to make sure it's not stuck open or dirty allowing gas to seep into a cylinder and into the oil.
Another more common reason for smoking is debris under the engine shroud. Could be mouse nest or built up leaves, grass clippings, etc. The engine will run fine at startup but as soon as it heats up enough then the combustibles will start to smoke. This is dangerous for two reasons. The main reason is engine overheating, which can destroy an engine. The other is an engine fire - less common but just as destructive.
My Husqvarna riding mower was smoking big time. I'm pretty sure it had to much oil, so I changed it & it was ok. 2 weeks later started it up it again smoked big time. That was the last time I would have used it as grass cutting season is over. I'm not sure what to do, but mower has full tank of gas, maybe I should start it & let it run to see if the smoking stops.
I look through your videos and couldn't find anything like the problem I am having. I have a Cub Cadet 46" RZT L with 190 hrs. The mower will start at times and works great. Other times it want start as if dead battery, battery is good btw, can't hear anything when trying to start the engine. Example: Cutting grass and stop the mower to take a break return starts right back up no problems. Then another time after stopping when I return no start. Go back in and after mower sets awhile or sometimes overnight it starts. I do my own maintenance being a retired Navy electrician / mechanic. Any suggestion. Tks
My weed eater is smoking bad! I installed new carburetor and spark plug but it smokes white after few min running. Can my oil have gas in it? Does my weed eater have a fuel pump? I have a craftsman thank you!
I layed my miser in its side to fix a belt. It’s been smoking and sputtering ever since. I drained and replaced oil and also put in new spark plug but still smokes and sputters. What should I check next?
I have a question for you about a rider that smokes but not like an issue you explained. This mower only smokes after it’s sat for a week and only on start up. After a minute it clears up and won’t smoke. Any ideas?
That's what I was wondering, my mower does the same thing. If it sits for more than a few days, it smokes for the first minute or so after startup, then stops. If it only sits a day or two, it won't smoke at all. It only does it after sitting a few days or more, which is the part that's really got me stumped.
Any idea why a brand new Briggs ex1750 would smoke white profusely then begin knocking. I have had this issue with 3 engines now and this one was bought brand new and it is fresh oil, I do have a bit of an angle I have to mow on but I’m at a loss
@@Mechanical_Mind each time it has happened on each motor it was on a slope or incline. I have had it happen going uphill and also on a lean and this new engine after to smoked and knocked on a lean I waited a few minutes and on the same lean fired it back up and smoke cleared up but it’s done it twice now.
I changed my head gasket and it's now blowing Black smoke. When I took the spark plug out, there was oil residue on it. Is that a possible piston ring issue?
Black smoke is usually too much fuel/ unburned fuel. Let me get a little more info.. You said you changed the head gasket and NOW it's blowing black smoke. Was it smoking before you changed the head gasket?
@@Mechanical_Mind it was blowing white smoke mostly since oil was dripping onto the exhaust. Now the engine is running rough even after I have adjusted the valves to the manufacturer settings and lots of black smoke. The spark plug has some oil residue on it , wasn't blowing black smoke prior to changing head gasket
@boudoirbyrdmimagery With it running poorly and black smoke, it could be a carburetor issue. I'd double check the linkages are all hooked up properly. Also check for possible vacuum leaks around the intake manfiod gaskets and carb gaskets. The black smoke might be from it burning off the oil residue that got inside the exhaust prior to the new head gasket. Not sure if you changed the oil or not but I'd check the oil for signs of gasoline getting in the oil. The fuel pumps can go bad and start letting fuel into the oil and oil into the gas.
@@Mechanical_Mind I changed the carburetor and it stopped smoking so the smoking issue is fixed. Now it's backfiring at times, I have the valves set to intake .004 and exhaust .006. Any other ideas? Fresh oil change, spark plug, new oil filter and air filter, belts etc
What engine model is it?? First I'd check for vacuum leaks around the carb by spraying some carb cleaner around the new gaskets. And there are times where a new carb out of the box has issues. I'd double check the valve clearance. I always rotate the engine over a few times then recheck the settings. Normally on the engines I work on the valve specs range from .004 to .006 for both valve so I'll shoot for .005 and after double checking if this with in that .004 to .006 range I leave it alone. If all that is good I'd do a leak down test to see if the valves are seating properly. You also could have a broken key for the flywheel causing the timing to be off a little but that is rare.
My problem is I was mowing. Apparently my lawn sank from an old tree stump rotting away from 35 yrs ago. So I ran into the dirt in my yard a few times trying to get out of hole. What would be the result from the mower slamming into the side of hole. Hope u understand what I meant. I hope I didn't Crack the head gasket.
Currently having to deal with the local Cub Cadet dealer as my XT1 L42 is blowing therough engine oil. Dwaler is saying its lack of air filter maintenance (despite it gets a new air filter every 25hr servics- currently on 90hrs); they are arguing the ride on shouldnt be used in a dusty enviroment- wtf? (Because of the cheap and half arsed designed air intake system, dust gets in and has scores the bore- requiring a new engine ($1520 AUD) or a rebuild ($820 AUD with 12 week wait on parts). Waiting to hear about warranty, and will build my own intake system with proper dust seperation with Donaldson filter
Im assuming they did a leak down test to determine the oil consumption is from worn piston rings. If so what was the percentage of leakage? Id also expect pics of cylinder wall scoring as additional proof it caused by dust. Intake design would not have anything to do with dust getting past the air filter.
It could. Does your engine have gas in it? Here is a video showing a trick to see if your engine oil has gas in it. th-cam.com/video/RMEMASwF7dk/w-d-xo.html
A little bit confused on this subject. My pressure washer has not been used in over a year. Started to pressure wash the driveway; started right up, seems to run ok, but after a minute or so it starts emitting black smoke; not white, not blue. Was afraid to continue. It doesn’t have a dip stick, just a plug on each side. Air filter looks good; it’s just a foam pad, no pleated paper. Since black smoke indicates unburnt fuel is there a danger to the engine if I temporarily proceed long enough to do the job and try to solve the problem later?
It might be the carb is minda gummed up from sitting so long. Try installing a new spark plug and fresh gas with some fuel addictive like Lucus fuel treatment. Then use the pressure washer for a good 20-30 mins to see if it clears up. If it doesn't clear up Id bet you need a new carb.
@@Mechanical_Mind Thanks for the prompt reply. The fuel has a treatment in it that I added when I last used it. I think that’s why it started so easily. I’ll check the spark plug first thing tomorrow. Now that I think about it, I believe the manual may have said to add a little oil to the foam air filter. I would have done it a year ago also. Also wondering why it doesn’t have a typical pleated paper filter. Washer is over 14 yr old, and has a Subaru engine. I was surprised about that when I bought it new. Thanks again.
Would this be normal on a brand new mower? I just got a John Deere Z320m yesterday, ran it for about 20 minutes with no issue and then today it is smoking like crazy!
I would like you to give me an answer if possible I have a john deere z915B that is burning a lot of oil it does not loose power but it uses about 1/2 quart every hour it only smokes a little after it has been working for more than an hour
If it’s not smoking then it’s not burning it. I’d look for a big leak somewhere. It could be the output shaft seal and could be leaking right under the engine onto the ground without you noticing.
Your fuel pump is probably allowing gasoline to enter the crankcase. Here is a video I did explaining that in more detail th-cam.com/video/RMEMASwF7dk/w-d-xo.html
So im on here about my mower but u said something about the gas and oil miixing and so my question is i have a generator i got year ago and it did and does start but i killed it and rechecked the fluids (oil) and i noticed that it smelled like gas bad know i have poured the oil out and poured some through it and refilled and it seemed cool so started it again well i killed it and checked again and it had a slight gas smell again so if possible i need some advice lol
It's important to cut the fuel off with the fuel shut off valve when the engine is not running. Also, your fuel shut off valve could be bad, letting gas pass by it even if it's closed. When gas is allowed to gravity feed to the carb it can easily leak into the engine cylinder, past the piston rings and into the engine crankshaft case and mixing in with the engine oil. You can check to see if your shut off valve is leaking by removing the hose past the valve going to the carb and see if gas is dripping with the valve closed. Some gas will be in the line so let that dry up / wipe it up and see if it's dripping after several minutes
Mine used to smoke, now it just vapes lol. My FR691 in my scag liberty Z smoked just like this for 15 mins and filled my garage It would smoke lightly after that from time to time and no it was not overfilled or the engine was not tipped in a weird way. Reached out to the dealer and kawasaki, and I never heard back from them. It regularly consumed oil, about a quarter of a quart every few hours... I've owned several Kawasaki's and never had that problem. , the engine did this when it was brand new
Hello, I just replaced the drive belt on my John Deere 1542hs and it was running fine. I drove it twice up and down my lawn and it made pop sound with white smoke and stopped suddenly. What happened to my lawn mover?
@chris2345 Popping noise and engine stopping suddenly is never a good thing. I'm guessing you have some internal engine damage. It's kinda hard to know for sure without inspecting it in person. If you want you could email me some pictures to mechanicalmindchannel@gmail.com and I'll try to guide you along to figure it out.

Does the smoke clear up after a few seconds? What color is the smoke?
@@Mechanical_Mind yes and white
@travel_eR. It might be just over filled a little on engine oil. It's actually pretty common to see them smoke a second or two at start up.

Would this be normal on a brand new mower? I just got a John Deere Z320m yesterday, ran it for about 20 minutes with no issue and then today it is smoking like crazy!
I bet the valve cover gasket is leaking and dripping oil on to the exhaust. New ones come in with that issue all the time
@Mechanical_Mind Dang dude thank you! That is exactly what it was. You are the man👊🏻👊🏻
I would like you to give me an answer if possible I have a john deere z915B that is burning a lot of oil it does not loose power but it uses about 1/2 quart every hour
it only smokes a little after it has been working for more than an hour
If it’s not smoking then it’s not burning it. I’d look for a big leak somewhere. It could be the output shaft seal and could be leaking right under the engine onto the ground without you noticing.
you forgot possible leaking VALVE cover gasket onto muffler
I have a brand new 0 turn John Deere that won't start. It started for a bit and had white smoke and now won't start again.
Any ideas?

I have a opposed twin Briggs that shows to much oil but after I run it and it’s where it should be. Why is it like that?
Your fuel pump is probably allowing gasoline to enter the crankcase.
Here is a video I did explaining that in more detail th-cam.com/video/RMEMASwF7dk/w-d-xo.html
My Ego mower smokes like that too. Can't find the dipstick on it to check the oil 🤔
Isn’t your EGO an electric mower?
So im on here about my mower but u said something about the gas and oil miixing and so my question is i have a generator i got year ago and it did and does start but i killed it and rechecked the fluids (oil) and i noticed that it smelled like gas bad know i have poured the oil out and poured some through it and refilled and it seemed cool so started it again well i killed it and checked again and it had a slight gas smell again so if possible i need some advice lol
It's important to cut the fuel off with the fuel shut off valve when the engine is not running.
Also, your fuel shut off valve could be bad, letting gas pass by it even if it's closed.
When gas is allowed to gravity feed to the carb it can easily leak into the engine cylinder, past the piston rings and into the engine crankshaft case and mixing in with the engine oil.
You can check to see if your shut off valve is leaking by removing the hose past the valve going to the carb and see if gas is dripping with the valve closed.
Some gas will be in the line so let that dry up / wipe it up and see if it's dripping after several minutes
@@Mechanical_Mind alright i will check that out and ill let u know and thanx thatll give me a start
Will it smoke if the oil is too low?
Yes, if the engine has been running for too long with too low of oil, it will cause damage to the engine that will cause it to burn oil and smoke.
@Mechanical_Mind thank you for th3 reply. Hopefully no damage done. Seems to be running good now.
Can i run 87 octane w ethenol???
Yes. Ethonal just eats away at the rubber fuel lines over time.
I see almost as many times that they put 2 cycle fuel in the tank.
💯🔥🔥
Kinda looks like Eli Manning for a second
your video don't help me at all, if you come to my house and make my mower starts that will help
Bro solve your own problems if you can’t get an idea of what to do from this video then you are mechanically DECLINED
Amazing comment
Great job
Great job
You can't just watch the video and it'll fix your mower you actually have to touch your mower
Mine used to smoke, now it just vapes lol. My FR691 in my scag liberty Z smoked just like this for 15 mins and filled my garage It would smoke lightly after that from time to time and no it was not overfilled or the engine was not tipped in a weird way. Reached out to the dealer and kawasaki, and I never heard back from them. It regularly consumed oil, about a quarter of a quart every few hours... I've owned several Kawasaki's and never had that problem. , the engine did this when it was brand new
Good video
Hello, I just replaced the drive belt on my John Deere 1542hs and it was running fine. I drove it twice up and down my lawn and it made pop sound with white smoke and stopped suddenly. What happened to my lawn mover?
Is the white smoke coming from the engine or the new belt? Did the new drive belt break?
The engine, all around the cover
@chris2345 Popping noise and engine stopping suddenly is never a good thing. I'm guessing you have some internal engine damage. It's kinda hard to know for sure without inspecting it in person.
If you want you could email me some pictures to mechanicalmindchannel@gmail.com and I'll try to guide you along to figure it out.
Ok
