Poor fuel economy is often a sign of a carburetor that is out of tune, resulting in a rich mixture that wastes fuel. Tuning the carburetor to achieve the proper air-fuel ratio can help improve fuel efficiency, so consult a professional or use a tuning guide for appropriate adjustments.
Backfiring can be a serious issue, often caused by a lean air-fuel mixture or timing discrepancies. To address this, check and adjust the timing settings and ensure that the carburetor is not running too lean by enriching the mixture as needed to prevent further backfiring incidents.
