Lately if I haven't started my '63 in four or five days it seems that the carburetor has gone dry. The starter cranks for an extended period of time and the engine doesn't come close to firing. I have resorted to pouring a little fuel into the carb to save the starter and battery. This gets it started and it runs fine. It also starts fine after sitting a short while - a couple hours or so.
The fuel pump is new and there is always fuel in the glass bowl of the fuel filter. This, along with the fact that it runs fine after it starts make me believe fuel delivery is not the issue. The carb has not been rebuilt for years but has been very reliable until now.
Time for a carb rebuild or any other suggestions?
