You might have pulled a lot of trash from the bottom of the tank. Take off the screw in filter on the carb.Blow on the hose inlet side of the filter. If it is at all restrictive replace it.
If possible you want to drain and flush the tank. Be very very careful on the drain plug. Use BB Blaster , and if the bottom of the tank starts to flex,stop. There have been cases of ripping out the bottom of the tank. Then you will be pulling the motor and spending large $$$ to replace it.
Good luck.
