8n ford will not start unless pulled

PAT SOELTNER Hi trying to figure out why my 8n ford will not start unless pulled starts runs well if turned off you have to pull it to start. converted to 12 volt started great for about a week put a new carb on it not any better just will not start unless pulled
mark sr A little more info would be helpful. Is the battery fully charged? how fast does the engine spin when using the starter? Converting to 12 volt shouldn't prevent it from starting unless it was done wrong and the battery isn't being charged properly.
ponymare Something is taking all the current from the coil while cranking, maybe the starter is really bad and drawing all the current.
Bob in KS What are you using for coil in your 12 volt conversion?

Original 6 volt coil with added resistor
Direct 12 volt coil (no resistor required)
Direct 12 volt coil with added resistor that came in conversion kit.

If original 6 volt coil with resistor, check to see that the resistor is close to 1 1/2 ohms. If more than that jumper around it and see if it starts. If so get 1 1/2 ohm resistor. I've seen several conversion kits that have wrong resistor included.

If direct 12 volt coil (no resistor required) and you have added the kit resistor, remove it.
