Earlier you said your mains were 165's. Now they are said to be 190. Is that correct. Way too big.
If your venturis are in fact 41, the car will be totally undrivable for the street.
41 is the largest that Mikuni makes. I recommend size 34 for the street.
Then drop the size of the main and air jets.
My mild L28 current runs the following.
Venturi 34
Main 135
Air 180
Pilot 60
