SBN 44's on a 1200r motor
Im using a protec manifold to run 6- SBN 44's on a XR1800 with pod type arrestors .
1.5 ns, 95 gm springs , 120 mains and 105 pilots with choke plates removed.
Oil injection still intact .
Both engines have Awful acceleration off idle, falls on its face .
Mid range stumble untill 5000 rpms, then its take off cleanly to 7000 rpm.
Anyone have a jetting baseline for non I-bodies on 1200r .
This boat was atheft recovery , missing carbs and ignition boxes.
Thanks go out to Hydro and PhillGpr for supplying ignition boxes
to get this boat back on the water

Move to 2.0 n/s and 110 Pilots. On a 48mm carb setup we ran 115 Pilots.
Your main jets may be rich but better stay there while you clean up your bottom end
