starter solenoid position has moved, this can happen when tightening nuts,

- first: get some starter spray and spray some in the air inlet at the air filter - then IMMEDIATELY start it. may need several trials. - second: push the Vespa in neutral some meters until you reach a certain speed and then switch from neutral to the first or second gear - then push further with some speed until it fires up the engine. you can do it best on a flat road or even better downhill....

The float pushes a needle that then stops the fuel flow make sure its not the needle thats sticking or what ever pushes on the needle is not sticking ! But if you are sure it is the float that is sticking a fine sand paper (320 ) can be used around the sides of the float to smooth down any rough bits .

- mine did the same - but also after it was parked there was often a sound coming from the engine for some minutes. There must be some air bubbles in the water-cooling system which was not drained properly at the factory... - don't worry - after about a year it will stop making such silly noises.. Cooling system Vespa GTS 300 ie 2009 2012 USA

- this problem might be a worn variator belt/rollers - Vespa technology requires a variator-belt service every 10'000miles - contrary to the belief that the carburetor causes such trouble...

There are normally 3 things that an engine needs to start. Fuel, spark and air. Start by checking if there is fuel to the engine, this can be done by removing hoses or at the bottom of most carburetors there is normally a small screw to drain the bowl of the carburetor. loosen it until fuel comes out. No fuel is a fuel problem work backwards from there to the tank. Consult the trouble shooting part of the manual also. There should be a step by step process. Next by checking if it has spark, take out the spark plug and put it back into the plug plug lead, get someone to hold it by the rubber bit against a metal part on the Vespa, not aluminium, the steal frame is good but pick a place where the paint has worn off. A spark should cross the electrodes, nice and blue is good, yellow is weak. Ensure all connections are clear of oil and dirt, if not clean them. Next check the air filter/cleaner, normally under the seat near the carburetor intake. If the filter is dirty, clean it or replace it. Good luck,

oil seals leak because the shaft is not held true in the seal check for bad bearings or bad adjustment of the bearings and shaft

The clear one connects to the battery vent connection and vents under the vehicle. The other two likely are overflow hoses coming from the carburetor to prevent engine flooding if the float valve is not sealing well causing gasoline level to get too high. They are open to the air.
