Anyone have the specifications for the spring; more specifically, for the 1931 smaller engine? I am checking my car’s spring.
For what it is worth, I measured my 1935 845 original spring having a free length of 2.12″, OD .407″, wire .0615″ dia. I don’t know if it is the same for 1931, but you could check yours. The same spring was used 1933-’35 at least, part number 703795.
If it seems to be the same, I bought a pack of the closest facsimile I could find and have extras if you need one.
Hopefully someone will chime in with info on the ’31.
