Something wrong with the ones you have?
Most times they don't go bad.I v'e never had to replace them unless they fall apart(one time).

FWIW, I replaced mine on my '69 70hp last summer. Not sure if it was age, chemicals in the gas, or what but they were old and were slightly cupped. They still "worked OK" , just not as efficiently. Once I changed them out it made a world of difference in the idle and overall performance. If you do replace them out be careful and take your time. It's an easy job that can go south in a hurry if you're not patient/careful...

The first and second stage are stuck open. have clean them but still won't seal. Have replaced the diaphragm and gasket but still idle's rough unless I apply gentle pressure on the bulb. Thanks for the part number, NAPA couldn't find it.
