there's a screw on the metering rod tree you can adjust to compensate for larger cams.
if you run outta adjustment on that, you can use a weaker spring that the tree rides on.
no need to drill holes just yet.



The screw on the metering rod try adjusts how far the rods enter the primary jets under full vacuum. Drop it and you lean out the cruise mixture, raise it and it will richen cruise.
