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? ![[Linked Image]](https://www.britbike.com/forums/ubbthreads.php/ubb/download/Number/17204/filename/Carburetor01.jpg) ![[Linked Image]](https://www.britbike.com/forums/ubbthreads.php/ubb/download/Number/17205/filename/Carburetor02.jpg)

i'm old enough to remember when patriotism meant not trying to overthrow the government.

Or, something else? ![[Linked Image]](https://www.britbike.com/forums/ubbthreads.php/ubb/download/Number/17209/filename/Carburetor03.jpg) ![[Linked Image]](https://www.britbike.com/forums/ubbthreads.php/ubb/download/Number/17210/filename/Carburetor04.jpg)

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. ![[Linked Image]](https://www.britbike.com/forums/ubbthreads.php/ubb/download/Number/17212/filename/Carburetor05.jpg)
