high altitude problem:vespa grande

I'm looking for advice regarding my vespa grande (1978). It runs pretty well at 5280' at all rpms. However at 7300' and above it has trouble at idle speeds and pulling away from a dead stop. Are there different jets available for this model's carb? Any advice will be appreciated.<br>
