At wit's end with push mower

[TomSelleckNumber1Fan]

Today I emptied and cleaned out the gas tank, ensured the fuel line was clean and free of debris, and filled the tank with high octane gas. I took the carb off, sprayed all the jets down with carb cleaner, and didn't see any obstructions in any of the tiny holes. I also replaced some of the seals and gaskets on the carb, including the pin and the seat that connect to the float.

If I spray carb cleaner in the carb throat, it will crank for a second or two, and then die. Outside of that, I can't get it to crank no matter what.

Anyone have any ideas?

Thanks

Post some model numbers for better advice.

Were there any tiny holes in the plug on the bottom of the carb? What about the holes up in the column above the plug? Did you clean/blow them out
too?

if it runs off carb cleaner its a fuel problem, could be vacuum problem too (meaning carb gaskets are shot - you did buy new gaskets with the new carb right?)

What i usually do (DONT DO THIS if you dont feel comfortable) is get it half running with carb cleaner or by jamming the primer button a few times a second and with the air filter removed i hold 2 fingers over the opening with just barely a slit between them (aka create a restriction) this causes the mower to try to run rich which it cant because of some carb fuel blockage. i have to hit the primer button a few squirts to keep it running and if it revs high completely seal the intake and should feel a vacuum pull which its going to try to suck air thru the open vented fuel system bringing fuel with it and usually sucking in and burning off water or other stuff.

whats the oil level at?
