Hello, I have a 1956 with a 28PCI carb on it The car runs great but I usually have to spray a shot of quick start in it to get it fired up after a day of sitting I noticed that the accelerator pump wasn't working so I removed the 4 screws holding it to the carb and noticed it was dry I blew air through the port to no avail What could be blocking fuel from entering the accelerator pump?
Thanks in advance |

The suction check valve or passage must be plugged. Pull the carb off and poke a wire or blow into the passage in the fuel bowl. It goes all across the carb to the pump check valve. Also take the screw plug out on the left side of the pump to access the other leg of that passage. That should blow straight through to the bowl.
Carb probably needs a good boiling out type of clean.
You can get the check balls out by removing the brass jet at the top when the carb top is off. Heat the carb with a propane torch or heat gun (hot to the touch) then the brass parts can be pulled out by twisting with small vise grips. The small pin inside the pump chamber is the upper limit for the first check ball. The heat trick works here too. I have done this successfully on many carbs.
If you are not equipped to do this perhaps find a good rebuilder or get another carb.
Good luck! |

Dan22,
Pulled carb apart and pushed a wire through the port from the float bowl and freed the check ball, blew through everything put it back together and it works like a charm Thanks for your knowledge and reply :D |
