New Issue- slight hesitation only on left turns

yeah agreed ...

is it a standard carb and is it facing the right way....?

a carb with its float bowl cantilevered off from the main bore of the carb i.e most of em

should have the float bowl in line with the direction of travel and as close to centreline of car as is possible. The orientation, is dependent on design of bowl and float, and dicates if the bowl is facing forward or back.
Any cornering means float is more submerged on one side and less submerged on the other. but its mounted on a parralel hinge that is transverse across the car, so average submersion across the deep and shallow fuel in the bowl keeps the float about same height.

it will droop or raise on brakeing or acceleration so the fore or aft direction of the bowl will have been chosen carefully by the manufatuerer to make for minimal impact

if its on sideways due to an adapter, or was designed for a different job, the bowl could be facing the inner wing on one side or the other. i.e use of a carb designed for a transverse FWD engine on a motor like ours.

The rock of the motor will have more impact. if it was a four cylinder the fuel would foam not so much on a 6 which has better balance by design

Similar impact will be felt in corners
one way float will droop massively causing too high fuel level in bowl
the other way it is pinned to the roof with the needle valve closed and the bowl begines to run low.

but assuming its a carb and manifold that was originally designed to be on this motor
float level setting or flapping auto choke would be my guess
