The carb on the QD 11 has a hose, called the "carburetor manifold hose." It’s plugged at the end…. with the "carburetor manifold plug," of course. What does this hose do?

DAVID,
I do not have your answer, but the Johnson Service manual calls it a Leaf Valve Silencer Tube.
Someone will know.

if you need the whole book….but as illustrated it does not describe the hose much…
Joining AOMCI has priviledges 🙂
It is supposed to make it idle more quietly. Replaced on later models with an air intake silencer.
I get the same effect by just shutting off my hearing aid . . . . 😀
Thanks, that item has puzzled me.
Thanks for the info!
