Hello, my name is Brandon. I recently bought a used two stroke Schwinn Stingray OCC off a guy who had tweaked and cleaned up the bike from the first owner. I am completely new to motorized bikes but have been looking at them for months. I really know nothing about tuning it up except what I've been reading on this site. Currently I've been having a problem with getting the bike to start and stay on before it dies, so far I don't believe it has even idled. I installed a wireless odometer to check the speed and it seems if I go any lower than 14 mph the engine will die. I've still got the old fuel in the tank but it's a 40 or 45:1 ratio, I do intend to drain the tank and put in a new batch to see if that helps at all. I've taken the carb off which I am very sure is a speed carb and the float is fine and everything seems to be in working order so I put it back on the bike. I opened up the mag cover since I noticed there was fuel leaking from one of the bottom screws. I'm not quite sure on my petcock positions to shut off the fuel valve but I did try to take the mag off in-case their was a leak but I can't remove it. The other part inside there is sort of a tea stained color and I'm not sure if that is normal or not? The original idle screw is missing but the last owner replaced it with another screw with a nut on it. I'm not sure if this is contributing to it not being able to idle and run or not. I was going to try checking the spark plug but because of the way the fuel tank is attached I can't get any tool into that space to remove it. I'm considering taking it to IFMC in Tempe to see if they can fix it, does anyone know if they are a good place to go? If anyone would like to take a crack at my problems please let me know or if you are in AZ and can help me with it or know a good place to take it to that would be great too.
