ekul,
The carby is not a problem if you stop and think about what you are doing. When you are trying to load the cable into the cam it is quite simple.
1. In the stop position the end of the cable should be approximatley 1/2" out.
2. You then push it into the side of the carby on a 90 degree angle.
3. If you have the correct amout out on the cable it should only just touch the other side.
4. Then slowly lay over the cable until it touches the cam.
5. You them move the throttle control until it moves the cam and it should work ok from then.
Regards,
