340 build No POWER need help w tune

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

26 38. 38. 26.

71. 25. 25. 71

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"
