Alright, i've been looking around various threads for the last few days, but still can't find a fix.
I bought a motorized bike last summer from a pawn shop. It worked when I first got it, but had some small issues. I'm young and have never worked on an engine in my life. I didn't realise that the issues were kinda ruining the motor. I just tightened all the bolts and screws and called it fine. Then my bike just wouldn't start so I left it for the winter since I didn't have the time or tools to work on it.
My bike was sitting for a couple months and still wouldn't start. I didn't know what to do and just followed some advice from trusted people to just replace the carb. I bought a new carb and throttle assembly and installed it. After I installed the carb it would start but the belt transmission was smoking, but I just took the cover off and it is fine. Now the bike starts on a closed choke and a little throttle, but tries to run away even after I close the throttle. If I let go of the throttle harshly the engine dies. If I open the choke it dies.
I've seen threads with similar issues, but none with all of mine, and none of the fixes work.
No one I know has any experience with small motors so i'm totally at a loss here.
