Hello everyone, I have a 91 SE that is running very rich...... richer than Oprah! The PO said he had the carbs rebuilt. Am I correct in thinking the carbs are altitude compensating like othere Honda carbs? I live at 2900 ft in Western AZ. We regularly travel from 3500 ft to 500ft ASL. Also, could the chokes be misadjusted causing the issue, or do I possibly need to rejet them?
Any thoughts are certainly appreciated!

Forgot to mention... has a K&N air filter that is clean.
