Most engines, when first started while stone cold, need to have the choke partially on to idle. The slightly rich mixture overcomes the poor fuel vaporization when the engine is not hot. As the engine heats up the fuel vaporized quite readily due to the hot engine internals and then the choke must be turned off.
As for needing to fight it for 100 yards, that seems like a carburetor tuning issue.
Do a search on this site for "carb tuning". You will get a "zillion" threads on the subject.
Oh, by the way, I am assuming that you have an NT carb? What carb do you have?

You may want to check that your carb is level. Look from the back of the bike towards your carb and make sure the bowl is straight level just eyeball it. Then make sure your engine is seated correctly so that the carb fuel bowl looks level when looking at it from the side of your bike. Make sure your bike is standing straight vertically and not leaning to the side on the kickstand while doing this. Stand the bike against your garage that's what I do.

The carburetor doesn't have to be perfectly level. In fact most installations will require a slight incline. You can accommodate for this by adjusting the float level.

The OP also asked about his rear sprocket and if it needs to be true. YES! Any wobble either horizontally or vertically will cause you problems. The sprocket must run true and be concentric with the rear hub. Chain tension and alignment is also critical.
