Modern Vespa

I have just acquired a 2010 LX150 that has a grand total of 38 miles and has been sitting for 14 years.
I don't yet have it in my possession.
I'm wondering about the carb. With the scooter sitting for so long and undoubtedly with bad gas in it, I'm debating the relative merits of rebuilding the original carb or just replacing it with a new one. Depending on what all might need to be replaced (jets, diaphragm, o rings, gasket, etc.) the difference in cost might not even be that much.
Any advice is welcome.

Welcome. Pretty sure that'll be fuel-injected.

Welcome to ModernVespa!

Welcome!

Yep. Welcome!

It did only 38 miles, brand new, but it sat for 14 years.

I expect there will not be any trace of fuel anymore, all evaporated. And the battery will be dead.

Do not spend money yet now.

I think these 2010 LX150's indeed have a carb.

I would start with only simply cleaning the carb, then give the engine new oil and check if there is spark. Use jumping cables and a battery from a motorcycle or a car whatever you have available.

If there is spark then put some fuel in the tank and try to start it. Can take several efforts but there should be improvement, from doing nothing, to a first bang, to several bangs, to running.

If it is alive try to keep it alive with the throttle for some time, letting it warm up a bit. Once it seems to run stable at idle see if it reacts normal to the throttle.

You'll have to answer that for yourself once you get the scooter and remove the carburetor. A friend gave me a Buddy 50 that had sat for 10 years. 1/2 tank of 10% ethanol gas in it. It was running fine, parked, and forgot about. The fuel melted the float and corroded everything so bad the jets had melted into their housing. The plastic fuel tank was fine, the fuel lines were in tact, the carb was beyond saving.

My mistake. Fuel injected LX starts at 2011.

Drain the old gas. Check the oil. Hook up a good battery and check for spark. If you have spark, pull the carb - it's a 5 minute job to remove, take pictures so you know where all the lines are routed. It may have a fuel pump on that carb model, so that will have to be tested too. Strip the carb down and take a good look at what you may need. There are no full rebuild kits for these, unfortunately, just separate replacement parts and they can run on the expensive side. Chuck all the parts into a sonic cleaner. Give them awhile to soak, remove and blow out all the passages. Check the diaphragm for suppleness. Now you can assess what you need and whether it is worth just buying a new one.
