Toro zero turn won’t start??

If you haven’t driven your 
Toro zero turn in a while,   or you ran it out of gas and it won’t start… first make sure you have some gas in it. Now look at your fuel filter. It 
probably doesn’t have any fuel in it,   and that’s because the fuel has 
to run uphill from the tank to get   to this fuel filter. So we’re going 
to detach the fuel-line right here. I’m going to hold the fuel line lower than 
the gas tank, release the clamp, and just   hold it down low, and just shake it a little. 
Fuel is starting to fill up the fuel filter.   Shake it until all that air comes out 
of there. Put the fuel line back on..
