What is the diameter of the hole behind the mixture screw in a P300 930 AMAL carb?

Thank you in advance.

Hi mrcarb, the #78 pilot jet drill bit is .016", so I would guess the hole would be pretty close to that. Hope this helps.

Do the following two photographs answer your question?

Are you referring to the plug between the front of the carburetor and the idle jet (first photograph), or the brass plug that seals the passage after drilling the two small holes (second photograph)? Or, something else?

MMs pic is the 2 stroke 68 set up with the PJ in the FB roof. Interesting to see the generous passages that the mung lives in.

Maybe it's too obvious to mention, but I'll mention it anyway. Concentrics came in left and right-hand versions, with the two internal passages reversed between the two.
