Hi Bernie,

before massaging the emulsion tube I would try a smaller air corrector jet. The smallest is a 0.80mm size. You should try that first.
You can also try a slightly larger main jet if that is not enough.

Modifying the F14 emulsion would imply drilling the inside well of the tube with a 3mm drill to a depth of 30mm and drilling 1mm lateral holes at about 28mm from the top. It would be a matter of drilling first one, then two and up to four holes and testing each time. The center hole can be plugged with a 3mm brass plug any time again and the tube would be back to original again.


I am glad to hear that my personal feeling about the good response of the F14 tubes has been confirmed on a dyno.
I am still putting my new engine together and have 8 42mm Venturis waiting to be installed. Will see how they work.
