Champion Lawn Mower. Model :-375 Sprint
Starts ok and works for about 3 minutes, then engine stops.
It feels pretty warm around the engine, oil level is ok.
After ten minutes it will start again and then same as above.

I have the same mower and had the same problem. I bought a new spark plug and touch wood problem seems to have gone.

Hi, my Mountfield mower also does this. Mountfields told my Dad that it's the diaphragm gone on the carburettor. In the case of the Mountfield the carb is a sealed unit and I can apparently buy one for about £14 and fit it myself. Please don't take it as gospel that this is what's wrong with my mower but it may well be and is one avenue for you to investigate
