Fuel leakage in the cap

When you tilt the mower in a few lawnmowers, fuel could leak into the carbon in the cap, limiting the fuel system’s venting. It can cause the lawnmower not to start up. Or the lawn mower won’t stay running, only run for some minutes, and then die.

In this case, you need to check that the gas cap vent hole is functioning or start it without the cap on to be assured. Leave the lid to dry out or substitute it with a new cap if it does not start.

Air filter problem

There is oil in the breather tube linked to the carburetor. Oil can then soakage into the air filter, causing a constraint and the lawnmower to not start after tilting or running full of fuel. If there is black smoke exhaust coming out of the lawnmower, this is possibly why.

You also can’t tilt the lawnmower, so the air filter is down. It would help if you always tilted it, so the air filter faces upward. That is why it will not start up, because the air filter is soaked, and no air can flow inside. In such cases, you can replace the air filter.

Due to the Carburetor problem

Fuel in the carburetor can cause leakage in the air cleaner and engine. This causes the lawn mower to flood and not start after tilting. Also, something can be lodged in the carburetor somewhere to cause the riding lawn mower won’t start after running.

The exhaust of the lawnmower gets very hot quickly at that time. Then, the lawnmower will also sound a lot louder than usual. It would help if you let the carburetor dry out or replace it to solve this problem.

Spark plug issue

If you store your lawnmower spark plug facing down after tilting, the Push mower won’t start after being on its side. This is because the maximum of the oil will find its way up that way, and it is hydro-locked.

In this scenario, you have to follow this properly.

Step 1: you need to remove the spark plug.

Step 2: Then, rotate it around a few times.

Step 3: Next, allow it to sit for some minutes.

Step 4: Then, re-install the spark plug.

Step 5: After that, try some starting fluids in the carburetor.
