I guess I’m not getting my point across that there’s a fairly good possibility your dyno sheet is not an accurate presentation of what those parts can make for power.
I wouldn’t, and dont, put much faith in dyno data that doesn’t really make sense.
Like I said earlier, I’d have less of a problem with taking the power numbers at face value if the fuel flow and bsfc numbers corresponded to the power output....... but they don’t....... and by a pretty wide margin imo.
I guess what I’m saying is, if I had it on the dyno here, with a known good carb on it...... I’d be shocked if the power and the bsfc, and the fuel flow all agreed with your sheet.
Unless(there’s always a caveat)........ there is something actually “wrong” with the motor.
Not the combo, but something actually malfunctioning or failing.
