I'm restoring a 1941 VC Case. It has the Continental F124 engine with a 6 volt battery ignition. What spark plugs should I be using? According to the manual, the original plugs were AC 75. Just wondering what is the correct replacement for them?

Thanks

I would think the tractor would use the same spark plugs as a VA or VAC tractor. I don't know what spark plug it takes, though. I know that I have good success with Autolite and problems with Champion in farm tractors.
 
Thank you for your reply. I'm not sure the VA series would use the same plug as it has a Case engine and the V series has the Continental F-124. I've also heard the champion plugs have some issues
 
We may have to find an alternative to Autolite in the future, Their parent company has failed to resolve some financial issues and is stopping production as well as Fram filters as I have read, How about some other of you guys search it out and see what you come up with, but that is my understanding.
 
Thank you for the reply. Some NGK plugs that came up are AB-6, B4h, 3320, and G-2Z. I'll keep looking. The plugs in there now are Champion D 21, but I was told Champion plugs for these applications are a problem.
 
If you give me champions I might throw them at you. I've had to much trouble with champions. I've had good luck with ngk. RB
 
I've used the NGK AB-6 in DC tractors and they work fine.
I'll have to look those other NGK numbers up and see if any of those are non-resistor plugs.

I read somewhere recently that some big company has bought Autolite, Fram ect and all of those brands (several) will be back in business.
I sure hope so.
