To Walbro Page Good news for racers running the Walbro WB3 carb.  From the 1998 I.K.F. Tech Manual, rule #616.7.4 Metering Diaphragms: May be captive or non-captive. Captive diaphragms may be modified to be non-captive, no other modifications allowed.
Now what that means, for those who sometimes wonder why their pop-off settings seem to be erratic, you should have consistent pop-off pressures by switching to non-captive. The captive metering lever sometimes binds causing pop-off variations. Walbro offers a non-captive diaphragm rather than modifying the existing one.
