ok, so I'm using cb's bigbeef manifolds, which are non-offset, my hex-bar carb linkage was for offset manifolds, so I bought the filter bases which are offset, so the hex-bar now sits straight...but now I have two problems:
1) I can't adjust the arms so the rods are vertical, as the right one hits the filter base, so I put it as near as I can before it hits.
2) as now the hex bar sits at a different distance from each carb, each rod has a different front/rear angle, so the carbs open differently and I can't get full throttle at the same time in both carbs
