I have a Briggs & Stratton 22 HP V-Twin OHV, Model 407777 on a John Deere LA145 mower. I bought it refurbished from Lowe's, and when I got it home it wouldn't start (no, I didn't ask them to start it for me at the store, at a $750 discount for a nearly new John Deere, I would have bought it whether it started or not). Anyway, when I turn the ignition key I get a strong whiring sound but there appears to be no ignition of gasoline. I removed the fuel line from the carb end and turned key to see gas being pumped out from the fuel pump. I next removed the plugs and squirted a little gas into the cylinder, replaced plugs, turned key, and ignition of the gas did occur but the engine still didn't start. What should I try next?
Sounds like you either don't have any spark or valves or out of adjustment
Take it back , it is still under warranty if you just bought it.

remove fuel hose from carb check that fuel is getting to that point then check if the hole the fuel line goes to is not plugged.
