If you’re suggestions of adding a small electric fuel pump is an option I will look into that.
No. Why add another point of failure? Fix what you have.

I covered all of the above With no luck.
Bottom line is Both vacuum and electric pumps not getting fuel to carb.
i parked it…might give it a shot next spring.

So the hose going TO the carb is plugged or highly unlikely the carb inlet port is plugged. Carb needle stuck closed?????

Pull the carb from the engine. Remove float bowl. Connect fuel line from pump/tank. Should flow into the carb bowl area dripping on the ground. You can test with water if you like.

Figure out why you are not getting fuel.

New carb. New fuel lines. New filter.
Engine runs fine if I continuously spray gas into carb from spray bottle.

Either you didn't get to it yet or I was ignored. Holler when you do more testing.

slomo…

Sorry, I wasn’t ignoring you. I should’ve quoted you in my previous post to acknowledge.
I think I have tried everything that everyone suggested throughout the thread other than attaching a vacuum gauge to the crankcase to get a specific reading. It does feel like there is plenty of suction when the engine is running though.
I just got fed up trying one thing after another and nothing making a difference.
Only one or two more cuts needed this year I think, so I’ll stick with the craftsman mower for now

I have a mid-90's Woods 6200 zero turn that has run fine since I bought it three years ago.
After sitting all winter, it refused to start this spring. I have pretty much run out of ideas as to what to check/replace next.
Use Stabil fuel stabilizer, year round. That way next season she starts like a new mower. Use it even during mowing season. Keeps your fuel fresh.
it will only stay running if I continually spray gas into the carb.
Fuel delivery issue and or dirty carb.
I installed a new carburetor, fuel pump, fuel filter and new fuel lines, including the hose from crankcase to fuel pump.
All new parts, require, testing. No guaranty they will work. Especially from Scamazon or Fleabay. Chinese carbs are hit and miss at times. Best to clean your OEM carb first. Then go to China World slash Amazon and get a new carb.
I primed the pump/filter/lines full of gas all the way to the carb but engine stalls out as it's not drawing fuel from tank.
Clean and flush the fuel tank, like a new one. Compressed air and so on. Clean her out like a hospital.

Also open the gas cap and see if she responds to a long shot, sealed gas tank.

and the fuel pump won't suck any gas from bottle either.
Did you connect the hoses back the way you found them? Was this a new OEM pump or Scamazon? You need a solid fuel flow AT the carb inlet.

Take pictures before you pull parts to reference later.

ILENGINE has a ton of good info for you.

There is no fuel, other than in the gas tank. No matter what, the fuel is not evenbeing drawn into the the fuel pickup tube in gas tank.
Remove the carb bowl screw or a drain screw if you have one. Remove the carb bowl. See if gas is coming out of the needle/seat. As in heading for the carb bowl but now the bowl is off.

Pickup, filter and all lines are not blocked or clogged in any way.
What about the fuel tank? Dude, start pulling hoses until you can find some gasoline. Start at the tank outlet.......... Open the gas cap. Let it flow.

If you remove the gas cap, and nothing flows out of the tank, the tank is either empty or plugged on the outlet.
