Just look at my air bleeds and these are the sizes.

Secondary
26 38. 38. 26.



71. 25. 25. 71
Primary

Hope this makes sense.

those 26's should be at least a 72. i would be 4 .075's and see what happens! unless you have a pin vise set then just remove the 26's and drill out to 71 and see what happens, .071"
