Finally swapped out the 090 carby for the OMC carby on my Pioneer 700D. Used a Joe Salva kit and it works great. Goofy carb, the metering gasket goes on top of the diaphragm instead of under it like every other carb I've ever worked on. Forgot that tidbit and wondered why it wouldn't pull any fuel and why the primer wouldn't work. And as it turns out, the original reason I ditched the OMC was not a problem with the diaphragms. One of the 2 idle ports in the throat was plugged and it would only dump fuel if the butterfly was too far open for the saw to idle properly. Only downside is the 090 carb venturi is much larger so I may lose some performance.
I may go after my other 700D based on today's success. Should I put my 090AV back together?
