Hello FiatSteve
That's an incredibly long run for a dealership!
I do believe there will be kill-switch wiring.
However, the Model 38 had different model numbers...
Example:

What we really need is the Model, Type and Code to know the exact
specification of the Briggs engine. As I guess you know, these are
stamped into the cowling.
Hope this helps.---------------------
