How do i stop my motorcycle carburetor from leaking gas? And i need some help with the starter and others…?
I own a 1982 Yamaha virago, and the carburetor keeps leaking gas very slowly. I have taken it apart a few times to try and see what was wrong, the floats in the reservoir on the bottom of the carb were stuck and i was able to tap them and they loosened up. The carb stopped leaking for a while but once i was able to start the bike up (was dealing with an electrical problem for a while *irrelevant*) its leaking again. It doesn't empty the gas tank when its on its kickstand, but when i sit on the bike and straiten it up/lean it towards the right side, where the carb is, a little pours out and then it slowly drips (1 drop every minute or so). Any advice on how i could fix it? And if it would be better for me to just get a new one (its old) where could i look to find something reliable and how much should i be prepared to spend?
Another thing, the starter is messed up, it works half the time, grinds the other half. Apparently everyone who has the original starter for this model and year of bike has this problem, i was gonna just buy a new starter, but i keep being told (by 2 bike repair shops and a dealer) that starters are bike specific, which im pretty sure isn't true because i work on cars too and starters for the most part are completely universal and interchangeable. I know bikes are every different from cars but im sure i could just get any starter...just looking for someone who could clear that up for me and give me a good place to look for a decent starter.
On a final note, ive been able to get my bike to start by using a car battery (not while the car is running of course), the starter turns (when it doesn't just spin wildly and grind) and the engine fires up with the help of starter fluid in the carb, it runs for a quick second or two and the engine stalls or just cuts out (not sure why its stopping yet). After the engine stops the lights and everything stay on. My best guess is that the car battery is able to give enough of a charge to spark the plugs initially to get the bike started, but once the engine starts running the alternator cant charge the battery (since its a full on car battery) enough to provide enough power to keep the plugs sparking, therefore the engine cuts off. Again, this is my best guess, i don't know for sure. Some other guesses or a thumbs up to that idea would be great, along with a few ideas to fix it if im wrong. I know i need to get a battery and im almost positive that's gonna fix the problem, just looking for confirmation on that whole deal. The battery i got when i bought the bike was completely dead, it couldn't even hold a .5 volt charge ( should be between ~10.5 and 12.6 for anyone who doesn't know that).
I live in Sacramento California, my bike is a 1982 Yamaha Virago 750cc (XV750)
-If any of you have an idea of how to fix any of these or at least diagnose whats wrong please feel free to leave your email so i can shoot you a reply if i need more detail.

For ur carb, please check ur carb needle, its too high, or the carb plastic "bubble" wrong direction u placed, else are worn pilot jet and main jet especially the swirl. For ur starter, ur pinion spring has worn, in car u can find the pinion only; but I don’t know how is it to bike.. For ur battery, u might can use car battery, bur remember the ampere of the battery could harm ur coil and magnet coil by high capasity of watt.
