What can I do if I put too much oil in my lawn mower?
You don't say if it is a 4 stroke or a 2 stroke. If it is 4 stroke, you must drain some out, you can damage the engine with too much oil, it is as bad or even worse than too little! You will find a drain plug somewhere near the bottom of the engine, normally on a corner opposite the exhaust sideIn a 2 stroke, if you know how much, you can just dilute with petrol, the ratio is not very critical as long as you are close. Otherwise, drain and refill with the correct mixture, you can add what is left bit by bit into the lawnmower or put it into a full tank in you car, the tiny amount of oil will do no harm in that much petrol. If the neighbours don’t mind, just top up with the correct mixture and ignore it as long as you did not use pure oil!
My mowers exhaust is smoking and smells bad... HELP PLZ?
Smoke in the exhaust is a bad sign. Usually it means oil is getting into the cylinder. If that's happening then you have bad rings. If the engine has a steel sleeve for a cylinder then you can hone it and replace the piston rings. But if the rings are bad then likely the bearings are also excessively worn. Unless you're ready to do a complete rebuild of the engine you might want to consider replacing it. If you have an "Over Head Cam" then there can be oil going down the valve guides. Which means you may have to replace the valve guide seals (not a difficult job), but you'll have to pay close attention to engine timing otherwise you can get the valves off sequence and it won't run that way. As for the carburetor, not sure what you saw or are describing. Usually there is the carburetor with a fuel bowl on the bottom. In that bowl is a float and float valve. Dipping into the fuel is a metering jet that allows the right amount of fuel into the carburetor. Get the mixture wrong and the engine won't run. There are various passages for choking and for venting the crank case. I have seen in some cases where the vent tube is blowing oil into the carburetor and smoke out the exhaust. You might have too much oil in the crank case. But I'd have to look at it to tell you more about what is going on. You say it smells like a burning belt. OK, even if you think the smoke is coming from the exhaust it COULD be a burning belt. For sure, check your belts to make sure there are no burn marks. Oh, and I say this with trepidation: DON'T CHECK THE BELTS WHILE THE ENGINE IS RUNNING. Why do I state the obvious? Because some people are foolish enough to check with the engine running. They loose fingers that way. Don't be a statistic, and I'm not going to be responsible for someone getting hurt because they misunderstood what I was suggesting. If it smells like a belt problem - check the belts. Maybe something is stuck and the belt has no choice but to slip (and burn) But if it's an engine problem fully diagnose the problem before you start throwing money at it. Hope this helps.

What is SAE 30 oil?
SAE 30 oil is a single-grade oil that falls within the viscosity grades the SAE has defined for a 30-wt oil.Understand that the SAE viscosity grades are completely arbitrary. A 30-wt oil has nothing about it that is “30” anything. Same for a 40-wt.What is a single-grade or “straight grade” oil? It’s simply one that does not meet the *additional* requirements for a second viscosity rating.It used to be that there were Winter weight oils (0w, 10-w, 20w, etc). And then there were Summer weight oils (SAE 10, SAE 20, SAE 30, etc).Technology gave us oils that can cover both winter and summer requirements at the same time. Hence a 5w-30 will be a “5w” when testing on the applicable winter viscosity scale, and it will *also* be an “SAE 30” on the summer scale.
