Hi Folks, I have a 1951 Lyman that has what I think is a gray 620 in it. I cant find a tag on it anywhere. The casting on the side of the block reads Y 400 A with some unreadable digits stamped after that and on the head it reads Y 400 A 418. I also found a 262 stamped on the back of the block below the head. Any ideas? Thanks

If it has a Zenith carburetor there will be a dime sized disc on it. On the carburetor, not the flame arrestor. Post the numbers on the disc.

It has a Zenith. The dime sized disc has an outer set of numbers and a inner set. The outer set is A84 then a gap and 546 2. The inner set reads 560 A then the letter S across from it. Thanks very much for any help you can give me.
