I just got a Champion 5kW duel fuel generator that produces a lot of anti-mosquito fog. I did check the oil dip stick and it appears to be the right level (after confirming the manual [online search] and what you said here). The motor seems to run smooth overall without extra popping or searching. The smoke did die down a little as it warmed up and as it reached full temp, it started smoking badly again. I'm guessing maybe there's a small crack in the gasket that's changing shape as the temperature changes. After watching this video my next diagnosis will be to check the head gasket. Thanks for the very informative and detailed explanation of what causes the smoke. And you kept it short, too. Awesome job sir. 😎
Best video ever thank you so much the reason mine was smoking was I had too much oil like you said, I tipped over the generator and filled it my mistake all day long but thank you..
One thing with honda gens with tank above sometime the needle valve in the carb can leak so engine sump fills crankcase up with petrol if oil pours out of oil filler it maybe fuel .this chaps done a great video 👍
would the blown head gasket also take a few second after start up to smoke ? I have a yamaha I changed the rings on and it looked absolutely mint inside and out. Even the rings looked fine. Changed the valve seal just as a precaution but didnt have a head gasket in my kit. After seeing your video, I think its seeping by the stock aging head gasket enough to cook some oil. The stock head gasket is metal but I will go ahead and replace it now, its smoking just like before. The head comes off relatively easily and I ordered a new head gasket regardless. Thanks for the info. The odd part for mine is it runs perfect first pull and then maybe 30 seconds running, smoke fog machine turns on and reeks of oil burn. Correct oil level and oil type confirmed, so going down the list now.
If I have the heads off and do not see any portion of the head gaskets blown out, cylinder walls are smooth, is there a way to test the piston rings as the cause?😊
I just did reason number one... just as you described :( if I let the extra oil out will it burn off the excess oil residual and be OK? Or will I need to take it apart and clean it before running it?
If it's still able to run and you now have the oil at the correct level, then it should burn the oil out of the combustion chamber on its own. Might take a little bit (depending on how much was in there), but you should see it become less and less.
Hey, I replaced the spark plug and I think I strip some threads, but it fits perfectly but now it’s smoking, is it because some aluminum slits fell inside? What should I do
probably also dropped some metal in there to score the cylinder. Dont attempt things like this if you are not even sure how to replace a spark plug. Sorry it may sound mean, but a spark plug change is a very simple job.
Mine only blows white smoke when I first started then it clears up and runs perfect, I pull the exhaust off to see if there was wet black suit Or dry fluffy which would be carburetor, I can’t figure it out and sometimes it doesn’t do it At all,any suggestions
Help me with this : I have a 5 hp B&S generator from 1980 or so. Has not run in many many years . I putted a bit wd40 on the piston to be sure and tried to start. The oil level was lets say 50 % full and I filled it with Sae30 and uber filled it . I filled it with fresh petrol and did not clean the tank . I had a few pulls and with starter pilote it starts . And stops - but when it starts running - it very hard to start - membrane will be new. I have never seen a BS burning oil like that . Put the oil level back at 50% and - smoke dissapeared almost . When I put the power to full, smoke ! When I choke the airfilter - white smoke ! I pull the carterventilation off - smoke continues when hand on the airinlet . I have compression, and no pressure in Carter . But I have compression in the airinlet, the choke clacks open en close - a bit air comes out the inlet of the carburator .. But still smoke . I checked the valves - one thing for sure The inlet valve opens snd closes, but does not rotate fast . ( marked it) Where do I have to look ? The head gasket? The valves ? They look good to me ? Just curious what people think . I love B&S and I can’t think this engine has ceased to be.. thanks in advance for the answers .
I have a brand new 22KVA (96A) Diesel generator and it’s blowing white smoke from the exhaust!! any idea why? is it possible because i’m loading very little on the generator? like 10-20%!
I have a wen 2350 watt generator it blows white smoke for a second when the engine revs up, but none while steadily running. I haven’t finished breaking in maybe it will clear up.
Do you know how long gour 6 volt batteries into two 12 volt can last with internet as ND 36* TV with fire stick,,? Any formula for watts used per hour if st 13,,, charge? I could understand this... thanks
Please answer: our generator is a 9.5 kva diesel engine, when I start it, the some is still normal, like no smoke at all, and later after it is running for almost 2 hours and the generator wil shake, and the thick white smoke will come out. What is happening? What should I do? (btw the only things plugged in are a refrigerator and some light bulbs)
I have a 800 Chicago generator or 800 watts I recently changed the carburetor to Wood but now when I start the generator I have to push the on button start it up and the middle of the choke and when I push the little choke button to the left to shut it down are choke it up it runs the opposite when I turn it off it doesn't turn off when I slide it back to the off position and I have to push the button to turn it off how do I
Thank you for the info on the smoking like gas now explain to me when I shut off my generator 800 Chicago Watts when I pulled the choke to the choke area it just runs normal when I put up to the off position it goes faster it doesn't shut off and I have to push the button to turn it off what did I do wrong I recently changed the carburetor
I don't even have 50 hours on my Duromax dual fuel and it's blowing white IF I can get it to even start. I thought it was from starter fluid plus a little gas in the spark cylinder. Pristine filters, oil is correct, gas is correct, new gapped plug. Ugh. Better not be any of these three as it's barely been used.
Good day, I have 2 questions, my Honda 3000 eu when I start it up it smokes for like 30+ seconds and smells like burnt oil,then stops smoking,. I also have a duromax 4000 that runs like a top, only thing I use it for a 2 inch submersible pump at work, it will pump water for a minute then stops producing power for like 30 seconds then back to pumping etc, frustrating when you're trying to pump a hole out at work
I'm aware that the old manuals on the Sportman 1000i used to say to add 10oz (I believe) which is too much and they would burn oil like crazy since they are supposed to only have about 7.5oz. My Sportsman just started blowing white smoke like crazy and I also have smoke coming from the dip stick when it's removed -- so I know that I have either piston rings that failed or a blown head gasket to allow that exhaust to enter the crankcase. Unfortunately, it's not worth the fix since I don't even think they sell replacement parts and the time involved into tearing into it is probably not worth what it would cost to buy a new one. I'm definitely upgrading next time to a reputable brand. If you have another reason to add as to why there's white smoke, I'd love to hear it. I love learning and sharing what I know.
@@HomeBatteryBank if you look at these Sportsman 1000 watt inverter schematic parts list you'll see what is called a one-way valve that's in the bottom of the crankcase mine was defective (bent)by high pressure the result-- I guess from blow by from the piston how that works is lubricating the rocker arm assembly on top of the head any overflow is taking back around to the carburetor when defective forces too much oil into the carburetor which then smokes
@@stublackwell Interesting! I probably have the same issue (along with dozens of other people on the forums). I was having oil run out of the air filter from the carb as well. I assume you scrapped your generator?

Thanks! Didn’t realize I was drowning in oil, appreciate the video!
You are the mosquito expert. Thank you.
Great information, thanks! I have an issue right now with a Toro Recycler that’s blowing a lot of white smoke. 👍👍
Great video man. Ive seen intake valve seals go bad too and leak into the combustion chamber. But yeah, mostly over fill or internal head gasket leak.
One thing with honda gens with tank above sometime the needle valve in the carb can leak so engine sump fills crankcase up with petrol if oil pours out of oil filler it maybe fuel .this chaps done a great video 👍

Great explanation. Thanks.
How would you clean the cylinder area if oil splash in the combustion area?
you dont, generator will just burn it out the exhaust. Self clean :)
Really good and informative video, thanks
Ahh yeah, so mine is a westinghouse wgen9500 and it starts hard, and puffs a second of white smoke. Thanks simple fix.
You are an excellent presenter. Great information, so helpful. Many blessings
Hey, I replaced the spark plug and I think I strip some threads, but it fits perfectly but now it’s smoking, is it because some aluminum slits fell inside? What should I do
You are pretty much screwed if you stripped the threads. Could try to rethread them with tap n dye.
probably also dropped some metal in there to score the cylinder. Dont attempt things like this if you are not even sure how to replace a spark plug. Sorry it may sound mean, but a spark plug change is a very simple job.

I over filled my predetor with oil, lots of white nasty smoke. After several attemps of oil removal the smoke dissapeared
Thanks mine was way over on oil.
I have a sportsman 7000 it is leaking oil from the muffler any ideal what is the cause for this. It starts and after a few seconds it cuts off
Thx for ur video it helped me bro🙂
I have a 5000 Honda generator and when I change the oil the oil come out like a milky why the oil come out like that
Good stuff helped out a lot
If this happens, can you still save the generator or will it permanently damage it?
General overfill it will fix itself by smoking less n less… that was my prob n a good stabilizer don’t hurt
you also forgot valve stem seals otherwise good content

Spot on this
What causes smoke out of intact valve
So my problem was caused by reason 1 but it han't turn off when I switched it off it just kept going
Thank you I did not know that
0:57 I did that, now I know 😂
Thanks bud

I bought this brand new Predator 212 maybe 2 weeks ago and it's blowing white smoke out the exhaust and won't stay running
Same with the generac I just got
Same here, too much oil in mine fixed ASAP with a good stabilizer
what if it's not white but just exhaust?
hi sir can you help me on genset problem
la ulan dere myloves
A "slinger"?
Stuck valve????
smoke is incomplete combustion, but I know were you are coming from
Ghanks I check smoke
That’s what she said
You need to research why the Sportsman 1000 watt inverter generator smokes it's not any of your three reasons
