I just thought of this: doesn’t the S36 use a pressurized gas tank to force fuel up to the carb? Watch the fuel air pressure gauge when idling and as you try to drive it. I think your car has an air pressure regulator, to limit the fuel pressure to the carb..

My feeble memory seems to recall around 1.5-2.0 psi is what you want to have. If you have too much pressure, it will overcome the needle/seat and flood the carb as the pressure increases with engine rpm [air pump rpm].

I may be totally wrong, but this might be one issue you could have.. you might try unscrewing the hand pump to bleed off the excess pressure while running the engine and see if it runs better with some pressure bled off.
