The mower runs for 10 mins then stops. Petrol leaks from the primer.
Is there something missing in the primer? e.g. spring and float?

If the bulb is actually leaking you can replace it complete with the white plastic cover. There is also an 'O' ring behind this cover that needs to seat correctly to prevent leaks. Also look for the line on the cover that has to be kept horizontal. The float and needle valve are behind the plastic cover - careful they don't get lost.
