petrol engine?

12 hp briggs stratton petprol engine runs for several minutes and then breaks down

Sounds like a fuel problem. REmove the fuel bowl, put a small container under the carb, turn on the gas and see if gas runs out without stopping. If it stops, you need to find out what stopped the fuel flow. I had a garden tractor do that and I found trash in the fuel tank. Cleaned the tank and no more problem.

Several possibilities, in order of likelyness (is that a read word???)...

1) Restriction in fuel line (dirt, deterioration, or both)

2) Float hung up (likely if stood with old fuel in it)

3) Water in fuel

4) Igniton coil failure (hot fail)

Hope this helps
