Terry, According to Guy Fay the B was produced starting in 1940, shared the
serial # with the A.   B + BN first year production was 12,764.   1940
serial # started with 6744  and went to 41499.  The dzus was used on the
early ones as was the choke cable kill switch. Just exactly when they
switched  I don't know. I've heard of them on some of the 40s.  Your # fits
in as a 40 .  Casting codes can put it to an approximate yr.   The B should
have a code on the engine a few inches under the mag. The format is
month-day-yr   so yours should end with the letter J.

Ever had the governor apart?  There is a spring in the end of the governor
gear with a pin that fits inside and pushes up against a button on the
housing.  Or do you have the type with the pin that is pressed into the
housing ?   Dont know the significance  but there is a difference.  Sure
makes the parts guys shake their heads.    Ivan

The original block has the same serial number as the tractor. That block was
cracked on the water jacket behind the manifold and I replaced it with the
block from a 1948 model C that a list member who lives near by sold to me.
I will dig the old block out of the shed and see what date it has on it.

Yes, I removed the governor and took it apart.  It has the spring and pin in
the end of the shaft.

I bought a parts and service manual on a CD from a guy who scanned them.
This sure makes it easy as I just print up a new page when I get too much
oil, dirt or grease on the one in the shop.  The parts book shows thw
governor spring and pin, so it must be an early one that he scanned.
