Re: stromberg 48 ???????
The 97,48 and 81 take the same emulsion tubes #36 (0.1065) and #57 (0.043) closing the small holes will effect performance make sure all holes appear to be circular in shape. Std. main Jets are .048 and #63 (0.037) power valve. Use the 0.098 inlet valve and fuel pressure between 2-2.5

The hole through the center from one end to the other, is the larger hole

Re: stromberg 48 ???????
so i gather putting a tap in them to extract them basicly destroys them as the bore will now be oversize

Re: stromberg 48 ???????
Tapping the end with a few threads, so they can be pulled out, does not make them bad.

Re: stromberg 48 ???????
They are not in there very tight. I have used a fine tipped easy out without any damage done.

Re: stromberg 48 ???????
I've pulled them out many times - sometimes I replace them with new ones from Clive (Stromberg 97). Usually they pull right out (I just tap the ends of them a bit and put a screw/nut on them to pull them out). Then I take a fine file to clean up the bore ends when they're out.
