B&S vanguard won't start after stator change

    I recently changed out the stator on my B&S 16hp Vanguard and now it will not start. Right before I changed it it started fine as I was checking the output of the stator. I have checked and it is getting a spark and gas is getting to the carb. I tried spraying gas in the throat of the carb a couple of times and it backfired and caught the gas on fire but it did not crank. This kinda makes me believe the timing may have got off somehow but there is only one way the stator will go on with the woodruff key, right? Any ideas of something I may have missed or put back together wrong?

    Check to make sure you didn't shear the key. I always replace them when I pull a flywheel. If its timed right it won't backfire.

    Remove the flywheel nut and insert a nail or a pin into the keyway...
    The key may have fallen out while installing the flywheel...

    To check for a missing key, do the above.( most likely scenario) Don't try runnin' it with a pin/nail etc.!!!

    I took it apart and it was the woodruff key. It had fell out and the flywheel was out of place.

    But then it still would not start because it was not getting gas. I blew out the carb and cleaned up the connection to the carb solenoid and then it started. So it was one or both of those things.

    Glad to hear you didn't run out and replace the carb, ecu or shortblock.

    I figured it was just something to do with me putting it back together wrong since it ran fine before.
