Ok, this is the answer I would expect.
What I'm trying to understand is,.....
If the diaphram ruptures, it would no longer hold the valve open, so where is any of this fuel coming from that is making the engine run rich, and supposedly filling the air box w/ fuel ?
I mean,.......
We have 2 senerios here, a slight leak of fuel that the engine would easily digest, and may go undetected for some time,
or a major leak that would shut off the fuel supply completely.
Where am I thinking wrong ?

The engine runs very rich,very quickly.On mine,it was black smoke rich!
I guess a smaller hole would be less rich,but rich nonetheless.
It's interesting because the carb gets starved for fuel,but fuel is being sucked straight into the intake boot,so the carb just becomes an air-metering device.
