I cant get this mower to start without spraying starter fluid in the carb. Just changed the oil, new plugs (checked and getting a spark), gas filter, new gas in gas tank. Lately every time I go to start it, I end up having to spray starting fluid in the carb just to get it started. If I don't, I end up running the battery near down cranking it over trying to get it started and can't figure out what is wrong. Once I spray the starting fluid in the carb, it fires right up and starts. Once it starts and runs a little, I don't have any problems running it but need to spray starter fluid in the carb every time I want to start it.

Suck, squeeze, bang, blow, in the right order and at the right time.  Can you feel air being sucked into the carb when you put your hand over the intake and rotate the engine?  If not, you may have a stuck valve or air leak.  If you can, you may have a plugged main or idle jet on the carb.  Do you have compression?  Again with the stuck valve or blown head gasket.  Do you have a good blue spark or just a spark?  A week spark is as good as no spark, especially if you have poor compression.

22hp Briggs Intek Twin.

Sounds like you have a gummed up carb or non functional choke.Are you putting the throttle Up the whole way into the choke position to start it?

 

Do you hear a Click coming from the front of the engine as soon as you turn the key to the run position?If not then your fuel solenoid may be sticking untill it gets jarred loose from the vibration of the engine starting.

 

 

Could be a couple things.If your willing to work on it a bit we can help ya.

Does this have a gravity flow from tank to engine? Or is the fuel tank in the back like my YTH150? It sounds to me like a check valve in the fuel pump is allowing the fuel to drain back to the tank. That would explain why it can start on starting fluid. If you could split the fuel line somewhere to check if it has drained back or not.

Ok we got it started... Like a few of you said, it was the choke.  The choke cable needed to be adjusted and was way out of position.  Got it adjusted and now running great.   

 

Thanks to all of you for responding!!!!

Glad you got it fixed. The choke cable slipping is one of the biggest problems but a easy fix once found.

I was going to blame the surge fuel pump mounted on side of the housing, cheap and easy to replace and go bad often.

Check for low float level adjustment or leaking carb intake gasket?
