Trying to see if our ‘49 we purchased runs. It has a 235 straight 6. We are converting to 12v so bought new 12v battery, new starter, new distributor & cap, new 12v coil, new plugs and wires, rebuilt carb, added a new ballast resistor. No ignition switch or new wiring harness yet so jumping it off from the battery and pouring gas straight into carb. Tested to see if we’re getting spark to the plugs and we are. Engine tries to start and hits occasionally but it almost seems like something shuts it down right afterwards! What could we be doing wrong? Maybe the battery to starter to ignition coil not connected right to jump it? We have the + on ignition coil wired to ballast resistor and negative on coil to distributor. Thanks for any advice.
