Not sure what a diaphragm carburetor is. Can you explain. It does have a plate on top that looks like it might be a cover on a diaphragm.
It has one adjustable jet. Don't know if it's the main jet. I assume so. I took it out and sprayed carb cleaner thru it. Then I finally adjusted it one turn further out than it was when I got it and it seems to be running ok now. Don't know if I cleaned some crap out with the spray or if it was just turned too far in to begin with.
