Hi all , just finished @ my mates cnc machine shop , as my metering blocks already have the vacuumn tube on them I choose to epoxy resin the original vacuumn feed hole by the pv ( above the check ball ) and then cnc machined a channel in the carb body to join the reverse L shape withinn the primary metering block - this then sends a vacuumn signal to the orginal area , so will fit carbs tomorrow and join both carbs together with a tee piece and then tee into my rear take off on my inlet manifold below the blower ,

Couldn't believe who easy it was , if your reading this and thinking off boost ref the pv and also have the vacuumn take off on the primary metering block , just do this mod rather than drilling the base plate as it looks more tricky , and I could see it being more labour intensive , you don't need a cnc machine , a steady hand and a drimmel would work ,

Thanks for the pv advise guys , off I go on another weekend of trying ,
