Has anyone had any experence with the flat top 260z carbs? and what can be done to them to make them better? i have never driven my 260z . its been sitting for about 3 years and hardly ran when i parked it. i know i should put my round tops on it but this is california so i have to keep it original or buy there $900 legal carbs . what a racket. anyway, please let me know if anyone can make them work . thank you very much.
