So, my bike was working fine for a long time, and then it randomly started needing a LOT of pedaling to get it going. Then, the throttle felt really loose. So I went to add tension, and NO MATTER WHAT I ADJUST, I can't get the throttle "tight". Now, the only way to get it going is to turn OFF the choke and pedal extremely fast. Before, I would have to start it with the choke on then turn it off, and it barely took any pedaling at all. I have tried replacing the throttle cable, the throttle, and have also tried adjusting the carb's pin plate. Thanks in advance!
