Bill I read an article once on reducing the OD of the (2) horizontle booster legs & reducing the dia of the choke shaft & as far as removeing it, John the carb guru at "the carburetor shop" says its better to keep it installed as it straightens the air flow & is very beneficial. Another tidbit was to use another gasket under the booster cluster to raise it for more airflow & shortening the vertical boosters. Can you enlarge the venturis bore(s) & booster nozzles, their ID?
