Then I suspect your pump shot is not lasting long enough. If you have 40 squirters front and rear and the cars leaves, then bogs - yet it does not bog from a roll, I am going to say I think you need a 50cc front pump.
If the above is correct, and you agree, you will need to order a 50cc front pump kit and the 50cc front pump cam. Don't forget the 50cc specific pump cam.

I think you need to take a step back and check the carb from the ground up. Lots of links telling you how to set up a carb for the first time. Put a big enough shot on there and it will get you through the WTFO test, but it will also mask whatever else is wrong and buck and stumble under normal driving.

Have a look at this image of the Holley pump cam assortment:
The 50cc pump cam is brown. If you look closely, you will see it is taller than the others. You need the brown cam.

I see that a lot. People put on the big pump and don't put on the taller cam. Without the taller cam, the bigger pump does nothing.
