Suddenly engine stop
« on: June 17, 2020, 11:34:28 AM »
I rode my 4t Like, after an hour ride full gas I stopped gasstation, filling up and resting five minutes. From there after 10 km, engine suddenly booaa aka. stopped running. Tried to start,and after few minutes firing up, slowly to home ok, and works and moves ok as before stopping. weather was 23 degrees celsius and sunny.
 What could have happened?

"an hour ride full gas"….do you mean engine was at full RPM for an hour?

Miles on your scooter?
Last service, including spark plug and valves?
Oil level on dipstick when this happened?

The screw that keeps the gas from venting of its own free will into my garage.

You can forget overflowing the evaporative emissions control. Gone with the wind is the phrase of the day.

Yes, around one hour full rpm, speed 45 kmh as limited. Miles around 9000 total, spark plug age I have no idea, valves ok, oil level ok, oil age one year/around 2000 miles.
 Works fine also today short trip, fires up in second cold or warm engine.
Next time at gas station no overfilling, thanks for the tip.
