I still have a problem - even after turning OUT the mixture screw on the carburettor:

1. When the vehicle is on the stand and I turn the throttle full, the RPM goes to 6000-8000RPM.
2. However, when I sit and drive it around the parking lot, the max RPM is no more than 5000 RPM and it rises and falls. I have the throttle turned FULL and I get the semblance that it may pick up and go more than 15-20MPH (ie 5000RPM), it does not.

Any pointers, please?
