idle speed and mixture
In this case, I think you should start with fresh petrol. Then there are 2 items to adjust / check;
- Idle speed, the large screw somewhere at the bottom of the carb. Maybe speed set too low?
- Idle mix - the factory setting is nice for new engines and to pass environmental laws. However, if you want an older bike to start and run well you'll have to adjust it as per my numerous other posts.
If all the above does not work, you'll have to clean the carb.
