toro zero turn briggs 18.5 not getting fuel to carb help please

Mower will crank with ur hand over carb and will run good for a min then start surging and die. Once it starts to surge if u put ur hand over carb it will catch and run good again for another min. I just bought the mower and it always did this but would never die, so i decided to take the carb off and clean it. Some of the small holes in the main jet were clogged, the fuel filter was dirty, and the tank was full off trash. I cleaned tank, put new filter, changed oil and filter, new plug, replaced the bad gasket between motor and intake tube, and made sure my valves are not to tight there good. Got it back together and im thinking its gonna be good and took forever to get it to crank and once it did is when i started having the problem i am posting about. Its like it has lost its prime and will not prime its again. My friend said there is suppose to be a pump on this model but so far i have heard it does not have one and there are no spots for the vac line. once its starts to surge u can pull fuel line off and there is no fuel coming out the line and the carb is up higher than the tank outlet. Is there a way to prime it so it keeps sucking fuel

 

I can't tell if you have a fuel pump or not, or anything about the carb without knowing what engine you have.

 

Please post engine model and type number and someone here will help you figure it out. Good Luck.

I don't see that model with a fuel pump. If the carb is higher than the fuel level, then I'd say it needs a pump. You can install a regular briggs pump or just wire in a low pressure 12 volt pump.
