Idk I would have to look, a guy restored it than passed away, my dad bought it off the widow and parked it in a barn in the early 90’s till my brother in law, a buddy of mine and myself pulled it out and hauled it to my house. After a rebuilt carb, new battery, new left side axel seal, new plugs and wires, new points and new cores on all the valve stems she started up and held air on the tires, well we had to pull it with my tractor for about 500 yards before it finally fired lol. It was back firing, throwing puffs of fire and making all kinds of racket than she fired off and purrs like a kitten now.
I would post a video off my phone here but it won't let me, only photos.
Btw the tractor is a 1953 Case SC
