65 c10 wont start

[65truckowner]

I am almost done with my 65 restoration. I cant seem to get it to start. It is a rebuilt 350 with a 600 holley and points distributor. It is in time and wired correctly. The carb is working like it should. I primed it the other day and it almost started but since then it wont even hit. I rechecked the spark and it was yellow and not the blue it was. Also the starter is dragging and turning the engine over slowly. I put a new battery on it today but still turns slow. I ran a hot wire from the battery to the positive side of the coil which did not make any difference. When I pulled the carb today to double check it the intake was wet down inside it but the plugs are dry. I am going to order a new starter tomorrow What am I missing?
