Make sure float drop is set to 15/16". Start with the acc pump in the middle hole. Move to top or bottom hole if needed.

Most "carb techs" dont check float drop but it is vital for an eddy to work right. Also the first step up on eddy carbs is a rod change NOT jets. Put it back to stock and reset float drop.

Check your vacuum advance canister on your distributor. That might be a vacuum leak. Leave it capped at the carb to rule it out.
