Hey all, I am going to cut to the chase, my scooter has been chugging, dying, and having a hard time starting, I changed the spark plug, and the problems continued, the battery stopped holding a charge, I brought it in to have it checked and it had a bad cell, so I bought a new battery. I rode it no more than 3 miles and it began spouting white smoke. I pulled over and inspected it and noticed the air filter box was dripping gas, I opened the oil plug and oil mixed with gas poured out. I read that the problem might be my valves, but I got bad instructions on how to do the valve adjustment and now the top valve is loose and I have no Idea how to get it back I'm at the end of my rope here idk what to do any help would be appreciated.

No the problem you currently have is the CARB IS FLOODING and gas is now getting into the crankcase and deluting your oil, It is not your valves causing the flooding.
The float is probably stuck or if you do not have a fuel filter on the gas line crap got into it and the may be blocking the shutoff valve. So you need to take the carb off and check the float and check if when level it pushs the valve up and shuts off the gas inlet.

sounds like your carburetor float is sticking.
In which case, you will need to of course, change the oil (and do that before anything else), pull the spark plug, and let her turn over to blow all the gas out of the combustion chamber with the starter, and then pull the carb, and either rebuild it or replace it (probably your best option here)... Carbs are not that expensive. If you choose to rebuild it, pay special attention to the float, needle and seat.
The float bowl on the carb, is like a toilet tank. It has a float that makes a valve close at the fuel inlet of the carb. If it sticks open (ie, the float has a leak) or the valve doesn't seat correctly, it continues to fill with gasoline (like a toilet running on), and can fill the engine with gasoline. This can be a really bad situation as it can Hydro lock the engine and bend rods, in extreme cases.
Then get the motor at tdc, and re-adjust your valves. I use .004" on both intake and exhaust, some guys use .003 and some .005.
If you don't run it, until you do these things, chances are you didn't hurt it.

so I'm kind of an idiot with these things and screwed up trying to do an un necessary valve adjustment and I lined up the t to the fin, but the big hole of the timing sprocket wasn't facing away from the engine and after adjusting it turned the fly wheel so that both the t and the hole were in their proper places. and now the arm that holds the assembly with the nut and screw for the valve is loose. is there any way I can fix it or did I pick a whole bouquet of whoopsie daises?

Just re-adjust the valves when everything is aligned the TWO LITTLE HOLES even with the top of the head BIG HOLE straight up and now you can adjust both valves. Alleyoop  |

 Here is how to adjust the Float, Now to test it put a hose on the fuel inlet and stick it in your mouth and hold it just like in the picture. Now blow into the hose and push the float GENTLY and if it seals the fuel inlet you will not be able to blow into it. That way you know the valve will shut off the fuel when the bowl is full.  |
