If you are trying to make it ride-able now, I would start by getting the idle mixture screws set as good as possible.

To do that, warm the engine fully and let it idle. Adjust the screws one at a time to get the highest idle speed. Then adjust the idle speed to 1300 +/-. I typically go about 1/8-turn richer after reaching highest speed, which helps smooth the transition off-idle. For now, just get the highest speed.

That's assuming the carbs are synced properly. If they were way off you may not be able to get a proper idle.
