If you have help have somebody start cranking the motor. Take a cleaned out Windex bottle, fill with a little gas and spray a mist over the carb. Done it many times and as long as you have a spark she will fire. You may have to mist several times to keep motor running, but it will finally pull gas up from pump.

Ok guys before you give me the devil, remember I'm an old retired firehorse and yes I kept a CO2 handy. popcorn The Truth is Out There (and that is the truth)
