loss of power upon acceleration

So i Hae some chinese moped thats 50cc used to run fine and could do 40+mph ut now something has happend i live in NY so i dont know if it is the cold. But when i turn on the moped it idles fine like a dream and will rev fine, but as soon as i sit on it and try to push the throttle with weight on it it bogs down after a couple of seconds any suggestions? it almost feels as if there is zero tourqe

Hi, Since you say that it dies with weight on, a fuel line is not being 'pinched' or that the wheel is not being jammed or brakes being applied. Sounds silly but can you transfer the 'weight' to see if it has any effect? Stand on the pedals perhaps instead of sitting down.

@supercarsny what make is your moped since you referred to it as a "chinese moped"?

@supercarsny sounds like some carb adjusting is needed to me. You want to start with the air/fuel mixture screw first. Also check your float height and make sure that the level is right and that the needle valve is not stuck.

the oil pump well kind of pump is over saturating the plug. best way to fix this is to bypass the oil line (block it) and premix oil and fuel and run that way. good luck
