1941 160 runs rough when warm. If i leave the car sit for 5 minutes and restart the car it will run smooth a few minutes, then eventually it will start running rough. The other day it was warm and i shut it off. About an hour later I started it again it ran smooth. I was thinking the coil or condenser may be breaking down when hot. I don not have the oringinal coil on the car its an aftermarket do to key switch is also aftermarket. I saw in the parts cross reference that a coil number should be Ic-1 but when i went to the auto parts the guy said it was a 12 volt coil so what other number would work 6 volt positve ground ?
