Hey. Did a ct90 engine swap to one of them 125cc Chinese jobs off Amazon. The thing just does not act right and I'm smart enough to know there is something I am missing. It'll start, kind of stiff but it kicks and it'll idle pretty good until it doesn't then it just a little hay wire. Up and down like the throttle is being pulled and dropped. Try to adjust it and I swear just touching the screw with a screw driver makes her go nuts.any and all questions and suggestions needed
