[img]i/expressions/face-icon-small-sad.gif[/img] Bought my son a taotao ata 110H4 with reverse, it will barely pull him in forward gear but when put in reverse it will fly. Adjusted thumb throttle screw with no luck. Anybody have a suggestion ?

 

This is the trouble with off-brand machines. They are poor quality to begin with, and nobody knows much about them, so can't be of any help.
