This sounds like the carb is plugged. Sometimes fuel thickens and makes globs...

If you verified the fuel flow to the inlet of the carb, then you need to take the carb off and open it up....
So, what needs to happen is you blow out all of the passageways with carb cleaner.

Any adjustable jets: make note of the position it is in, and FINGER TIGHT turn it clockwise until it closes (typically 1 to 1 1/2 turns) SOOOOO, you can set this jet back to the same positon....when finished blowing everything out, bottom the jet and back out the number of turns out, noted for that jet.

Open the float chamber, and clean as necessary, Inspect the float adjustment: invert the carb, and observe the angle of the float, relative to the carb body.... Usually almost parallel, but not necessarily.
Inspect the inlet valve, and clean those areas...

I usually use all new gaskets and valves, but if you are not a carb person, cleaning is effective and I think old gaskets may be okay, if not torn or damaged.

    on the bottome of the carb bowl you will find a selinoid. it will have one wire going to it. unsrew it and either replace it or take a pair of good wire cutters and cut the little rod that comes out. If the rod is not sticking out you can pull it out but with your problem it should be out already.

Why wont briggs and stratton 12.5 h run without choke?

Carb is dirty and before you tear it really apart take the fuel bowl off if it has one and clean it real good and blow the dirt out of the fuel jet which is the bolt that holds the bowl on .That may be most of your problem. Drain the old gas and replace with fresh as well. Won't hurt to run some cleaner through as well.

I have a 2005 Dixon zero turn mower the motor is hard to turn over but once it starts turning it turns fine when the motor starts it will only idle and not accelerate it has a 14.5 hp Briggs and Stratton...

sounds lie it's starving for gas.
Does this engine have a fuel pump or is the gas gravity fed???
Some engines this size do have fuel pumps.
I'd also take the bowl off the carburetor and check the Jet.

When trying to start fuel spits out of the carburator

Remove carb float bowl. Clean bowl. Get model no. of engine and get new float bowl gasket set at mower repair store. Ensure float drops down freely with float bowl removed. Push up on float to stop fuel flow. If not working properly replace float and meter needle.

Will not reach top hp exhaust cherry red

Your carb is in a lean codition which causes the exhaust to glow. I would recommend having repair shop rebuild carb .This way you get it set properly and should have to make only minor adjusments .I also recommened running a fuel stabilizer all the time .

Have a 3 year old 42'' Toro Zero Turn never had a problem. Was cutting grass and it died. Will not start, no fire and does not seem as if it is getting fuel ? Does it have a fuel pump or could it be...

That unit has a fuel solenoid that is attached to the carburetor bowl. Over time this solenoid can act up at odd times. You can take off the air filter cover and manually choke the unit and see if it will start up again. I would take it in to your nearest TORO dealer. On the website it has a dealer locator to find the closest one to your zip code.
