throttle bogs down

[supermanotorious]

I have a 70cc chinese bike which ran great over the last summer, now it will start but wont idle, it simply dies, plus when I shift into 4th gear and open the throttle all the way, it bogs down, what gives? If needed, I will mount my GoPro to the bike and shoot a video so you have a better picture of what I'm referring to. I am mechanically inclined so I can clean the carb etc if necessary but I'm hoping its something easier

I am not too sure what the problem is with your bike, but give the guys a chance. More than likely it is going to be your carb, but hang around to see what everyone else is going to say

Ok, I cleaned the carb real good and then put it back together, when it starts its all the way open, it's a vertical cable carb, is there something obvious I'm doing wrong? Why is it stuck in full throttle?

did you reconnect the governor linkage? that could be a problem. Also, the throttle cable itself could be too tight. you could loosen it up.

Also, the bogging down, that could be a problem with the trans/gearbox. Could be the carb or trans/gearbox really.
