I have just recently bought a meitian mt50qt-16 two-stroke for my wife. It has less than 15 miles on it and it seems to run fine for a while then all hell breaks loose. When you give it throttle she wants to bogs down and die. But it fires back up and idles fine but when you give it gas she wants to fall on her face. Then if you let it set awhile it starts up fine again and runs till she warms up (I guess) and repeats this process. If theres anyone who can help it will be greatly appreciated.
