The bike starts up fine, and will run and drive as long as you keep giving it gas. I took the carburetor apart and cleaned out the bowl, and it looks fine. Then I took the fuel injection switch off (It says On, Off, and Reserve) and the filter that is on top of it looks pretty weak. There looks to be a bit of bad gas in some of it, and the lower portion of it has cracked where the plastic bracers are. where it connects into the switch, and everything else is fine. When I start it up, it runs fine with full choke, and will run in choke off position as long as you keep giving it throttle. Do I need to change that filter on top of the switch, and if so, what is it called. I tried to do a search on google for one and couldn't find one. Thanks!!!

As long as your bike runs fine when you give it some throttle, the problem is with your throttle stop screw and/or the length of the throttle cable. Generally, if you make the outer cable longer, the idle goes up. There should be a throttle stop screw on the carb where the cable goes in. If you've already had the carb off and put it back on (don't laugh, a lot of people can't), you can resolve the idle situation on your bike.
You might try the library for a shop manual and read the chapter on carb and operation. Better still, buy yourself a manual from the shop. Even amazon.com may have a manual for your bike.
One other thought- if it runs with full choke, that means it might not be getting enough fuel. Once you sort out the idle, I'd take off the carb again and look through the main jet for a bit of crud. But this bike might just not mind running on full choke, with an overly-rich mixture. If your spark plug looks black after you've been running it, you might be burning too much gas. The manual will have a few photos of what your spark plug should look like.
And if you ever need to do anything else (brakes, bearings, etc.) you'll already have your manual. Good on ya!

If it runs with the choke on and dies when you take it off choke, that's the idle jet. The orifice is really small and if you don't have a jet drill use a small wire and carb cleaner.Its next to the main jet and looks like a little brass pipe. The hole in the top is not the orifice. Its farther down in the tube.It has a screwdriver slot or a hex head. The most common cause of this is when people leave gas in the carb for months and it goes bad. You have to take the float bowl off to get at it. On some s you can just loosen the carb clamps and turn the carb to the side and take off the bowl and then cleaning the small jet.
