bike needs more throttle to accelerate?

[jnewton]

so my bike broke down a few weeks ago. i wasn't sure what the problem was so i cleaned my carbs and all that. the problem was a contact breaker, but i don't think that is important? since i put it back together, it takes more throttle to get going. even from the get-go of starting my bike and leaving, i have to get on the throttle hard just to start out moving, and it starts out extremely slow at first especially. it's very loud and i don't understand what i did- if it was something with the idle switch, or maybe the throttle pulley system? even after i've started going, it takes way more throttle to accelerate like it did before i took it apart. it's a 77 gs750.

sounds like it's only running on 2 cylinders.
feel the pipes and see if all 4 are hot to the touch...if not you may still have some buggered points.
ex.
1-4 pipes cold
2-3 pipes hot or visa versa.
