I believe under the cover it has the same carburetor
as the 1938 Fleetwin I once had. (velocity stack is
my own addition.) The primer is problematic in that
it leaks. There is an O ring that will solve that issue
but they wear out quickly. There is also a check
valve (arrow) as part of the primer. If someone
before you decides its some kind of blockage and jams
something in there and destroys it the motor will start
but it does strange things that don’t make any sense.
After several years of getting nowhere Doug Penn
had the part and the answer. Also there are spring
loaded friction plugs for the mixture screws. If you are
not aware of this and you remove the mixture screws
the friction plugs can escape. I found i could make a
replacement from a piece of line for a string trimmer as
a substitute.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
