New carb on 49cc scooter. only runs for 30 secs
Sound like the float in the carb is getting stuck the way to tell is loosen the screw at the very bottom or carb and see how much gas comes out it should run forever if only runs for a few secs the clean out carb
Leaking carburater
The float valve in the carb is sticking or the float height setting is incorrect or the float has a hole in it.
Do not use Pri on your fuel tap until this is sorted as it could cause hydraulic lock in your engine, which will wreck it. Fuel will flow through your carb into the engine when it is parked.
This will also ruin your engine oil as the fuel will mix with it. Check the oil level to see if it has increased...
Spark plugs
Sort your carb settings out...it sounds like you have an over-fueling problem causing the plugs to foul.
