what make model of carb for '64 slant 225

find a good core, get a rebuild kit and either you or your mechanic can do it. there is an insulator (plastic) where the rod goes that is available on ebay. I have found some from members on slantsix.org. mine are 1920 Hollley. do you have the correct throttle rod and gas pedal to make it work. if auto, the kickdown? things to consider.....
