I have an old tiller given to me by my grandfather. It is a 5
horsepower Brigs. The carb is mounted to the gas tank. It would only
run with starting fluid for 10 seconds then shut off. I took the carb
off to clean it but there is a long pencil looking plastic tube from
the carb that goes into the gas tank. It has a screenon the bottom of
it. It broke off.

Do I need to replace it and what could be wrong with it not starting?

The B&S repair manual shows many different models and variations of
the Pulsa-jet and Vacu-jet tank-mounted carb. To find the right
instructions you have to determine the engine model and match the carb
to a set of drawings.

Try filling the tank completely full, to get gas into whatever remains
of your broken pick-up tube. In general the best-guess needle valve
setting is out 1-1/2 turns from lightly seated, but they say that's
only enough to maybe get it started, you still have to adjust it half
way between too lean and too rich.

Yes, if anything is broken or damaged on them it needs to be replaced,
good luck!. Sometimes disassembling them and blowing out any dirt
fixes them, but if you haven't done carbs before take pictures of
where the pieces go and be very careful not to rip any gaskets.
