PLEASE HELP - Cub Cadet Mower Model CC46ES Runs A Few Seconds Then Dies

If the engine busts off for a few then dies, you have a fuel delivery issue. Or old stale fuel is being delivered. This time of year, 99% of people left their old Ethanol E-10 in the tank and demand it start up next spring, which is now.

Plugged up mains and pilot jets. Wouldn't be a bad idea to flush the tank and carb bowl and dump in fresh 100% real gas.

I always use stabilizer as I can never recall how old my fuel is/was. Never a starting issue.
 
you really want the engine model number and serial before commiting to any parts, but a generic google search of what you posted yielded this. This is the Kohler engine (2012). https://www.partstree.com/models/cc...d-mower-2012/kohler-xt173-3316-fuel-system-8/

Some older ones (2010) of that model come up with a completely different B&S engine. https://www.partstree.com/models/cc...ind-mower-2010/b-s-122l05-0768-f1-engine-2-2/ That don't have the auto choke diaphragm. I have an edger similar to this and the pulses from the engine crankcase cause one of the gaskets under the carb to act as a valve in a fuel pump.
Here are the Mower Numbers:
Mower Model 12AE46JA009
Mower Serial Number 1F071K30583
Engine Serial Number 2P70M0C1010102A0314


The parts tree shows this Carburetor Gasket Plate MTD-951-11525 but doesn't show where it goes.
Does it go on first before the Carburetor?

I replaced 67 with the hose. Fuel flows freely to the carburetor. I checked the bowl. It seems to be fine. Gas flows freely with the cap off and the float dropped down. Gas shuts off when I push the float up though.
 
I have a self propelled Cub Cadet mower Model CC46ES that starts right up, runs a few seconds, then it dies.
Here are the numbers:
Mower Model 12AE46JA009
Mower Serial Number 1F071K30583
Engine Serial Number 2P70M0C1010102A0314

Here's what I have done
Changed out the gas
New Carb
New Fuel Lines
New Primer Bulb

If I press the primer bulb repeatedly after it starts up, it will keep running. When I stop pressing the bulb, it dies.
It is obvious it is starving for fuel. Change the filter, blow back line to tank with cap loosened. Turn ON valve if there is one. Remove float bowl and lift float. If no fuel comes out you have a plugged needle and seat. RE and RE.
