petrol mower cuts out

[Kos]

[bookbinder]

Yes, they do that, sometimes.

I've come across that problem occasionally, there are any number of reasons for it.

[tonyav]

Lack of petrol, bad spark plug or maybe the air / petrol mixture needs adjustment at the carburetor.

[andy-hughes]

Possible overheating which vapourises the petrol too quickly.

Try cutting your lawns at the beginning or the end of the day.

Oh, and a Question is considered polite, rather than just a heading.

Thanks!

Hot weather airlock would be my guess too.

Sorry- should have read.............
Unleaded petrol mower- starts, then cuts out after a few minutes, or lacks power. Spark plug coverered in black sooty deposit. Cleaned it and within minutes if wass black again. Any ideas?

[tonyav]

Your air / petrol mixture is to rich ( with petrol ).

[HowardKennitby]

Is this a 2 or 4 stroke motor?

[jomifl]

Knowing what make of engine might help. Briggs and stratton engines don't have a float chamber to flood so look for an air filter clogged with grass cuttings and oil.

Teenage son had turned the fuel supply tap OFF !!!!!!

[bookbinder]

Hm. You won't find that particular fault in the instruction book.

[HowardKennitby]

sooty plugs indicate something is not right regardless of other things.

[DTCwordfan]

service time - air filter, mix, airlock, host of things...

[jomifl]

It is always the thing that nobody thought of..
