Why is my scooter not running?

Ok, heres the deal, I have a 1985 honda aero scooter. It was running sluggish so about two weeks ago, I tuned it up, i cleaned the air filter, ran some carb cleaner/ injector cleaner/fuel additive thru it, and put in a new spark plug. It ran fabulous! For about a week and a half. Then i started it (started just fine) tried to give it some gas and it killed it. Started again, this happened 3 times. Now it wont even turn over! What the hell is wrong now? Help me before I drive it off a cliff!

It's to bad some people don't have the common decency to give you a normal answer.
Your scooter is 20 years old. The piston & rings might be seized to the cylinder (engine locked up). To check, remove the plastic cover on the right side of the motor (2 bolts). Try to turn the flywheel. If it won't move, it's time for engine work.
If it will move, could be bad battery, starter motor, starter solenoid or starter button.

You have blown a load in the air cleaner. Rinse it out.

take it to a local atv or motorcycle shop, either that or find a repair manual and good luck

I'm sorry, but as soon as I read your question I started to laugh. You sound exactly like my brother. I know this sounds so stupid, but did you check the battery? Let me know. You can email me.

is their oil in it? when was the last time you changed oil. if you ran it out of oil, the engine will not turn over any more

I am with stutzie, if it does not turn, it is probably electrics. check all connection, especially the lear from the battery to the chassis. Take the battery off the scooter and recharge it slowly overnight. Check the spark plug lead - sometimes the plug cap comes loose, also the point where it joins the coil. Is there a cut-out switch? These sometimes short so a bike won't start.

Its not running becoz it has no leg
