Well you have a leg up on it , if the pedal goes to the floor again change the master cylinder, got a bad one a few years ago and hit the brakes and went down to the floor , pumped a few times and the brakes cam back , after that it would slowly go to the floor , scary,and if you need any carb parts let me know , got a few cores if you want them , I went to EFI a long time ago , later Blaine
