I am new to lawn up keep but I like to keep my tools in good condition. A year ago I purchase a used Black & Decker self propelled push lawn mower.

I recently let someone else use it and she filled the gas tank up with 2 cycle mixed gas. She mowed half the yard and I noticed it smelled like burning oil and the smoke was dark. Finally one of the times she was starting it it let out a high pitched wine and didn't start. This is when I determined which gas was used. I drained the remaining gas and have not tried to start it again yet.

I looked on the internet and it recommended flushing the hoses I guess. Does anyone know how I could clean it out my self? :'(
 
Why is this in computer power supplies?

I'm under the impression that your mower is either a 4 stroke, or it has oil injection. Just replace the spark plug and run some normal gas through it - maybe get some injector cleaner or seafoam.

I have a couple questions: Why do you need to put gas in an electric lawn mover? And why is your first post in a computer tech forum about a lawn mower?

But for a gas lawn mower, get some carb cleaner and spray it through the hoses, then in the carb with the engine running. As mentioned, check the spark plug. You may have to end up taking it to get the card rebuilt though, but that shouldn't be too expensive

That would be a hell of a nice powerful mower. I bet it's a 4 cycle engine.

Give us the model number.
 
When trying to start it is there any additional resistance in the engine turning, suggesting it will need rebuilt? If not, do as Yuriman suggested, put fresh gas in and try to start it. If it won't start take the spark plug out and clean it off or replace it.

There's not much point in flushing the hoses, since the gas will do that and it had already ran quite a while on the oil/gas mix so it's not as though you're keeping very much oil from getting in relative to what already has.
 
Just re-fill it with new gas and start it up.
2 cycle in a 4 cycle won't hurt it much. (just hard to start, smokes a lot, etc.)
4 cycle in a 2 cycle can lock it up.

I wouldn't worry about cleaning any fuel lines out. The new gas will do that for you after it runs a few minutes.

Putting mixed gas in a four stroke should not cause any problems but a smokey exhaust. Running it low on oil will. But a "high pitched WHINE"? This machine an electric start and she craped up the starter?
 
I intentionally ran 50:1 in a B&S 4 stroke powered mower because it was all I had.

Other than having to clean the spark plug a couple of times to finish the lawn, I didn't notice any difference. The engine died whenever the plug got too fouled. The mower ran fine later on the proper fuel.
 
I wouldn't bother with cleaning it out. If you drained the rest of the gas, just fill it up with plain gas now and roll on. Any remaining oil residue will get cleaned out.

It shouldn't have mattered much, anyway, other than the smell and smoke. I've run 2 stroke mixed gas in my 4 cycle engines many times in a pinch when I was out of plain gas, never a problem.
