rebuilt carb issues????

[96clubber]

ok i do not want to spend 166 on a new carb so i am trying to rebuild mine with my old carb i had laying around.... on my carb the throttle shaft is fine to me alittle loose but where the shaft and the linkages bond together it is extremly loose there... so i was thinking last night find my old carb and see if that part was still good. i found the carb and that part is still good so i took the 2 little butterfly screws out and swapped them. i got gaskets today put it all back together. i dont believe this thing has ever gone this fast but....... once it gets warmed up it falls on its face... i am thinking dirt in carb???/
or is this another issue?


i am happy it runs fine until it gets warmed up then blah.....
