help! corolla won't start

i have a 86 corolla gt-s 5- speed but it has a 4ac carb engine. when i bought it was running fine turned on every time. brought it home and let it sit for like 4 days now it won't start. sometimes it acts like it's gonna start but it doesn't. Any help is appreciated.

check your battery it's possible that you may have left a light on or door and battery could have died. You can check by turning it on then try putting window down
