Kinroad Sahara 150cc woes

[H3llb1lly]

Hey yall I just got a Kinroad 150 a few days ago and it runs like crap till I go downhill then at about 20mph it pulls to 35 easy. But as I go back uphill it's slower than molasses, no power and spits and misses real bad. The exhaust is leaking at the head and I'm thinking that'll be part of it. I took apart and cleaned the carb and that seemed to make it worse. I sprayed carb cleaner over every piece of intake and vacuum line that I could and got no idle rpm variance. I'm at a loss on it unless it's the exhaust. The port on the head has ridges that follow the cooling fins on the rest of the head. Like someone filled in the head fins for the exhaust port as an afterthought. And did a bad job at it because one side is higher than the other. Any help it greatly appreciated. Thanks yall.

A leak will do that, also be sure to check cvt weights. Kid n me has some you tube vids of maintaince for these buggies.

What's the cvt weights? And what's the cvt? Constant velocity transmission?
