Kelly, pretty sure that your choke is not set properly. You could turn the
key on and listen for an electric fuel pump to run. That would fill the
carburetor float bowl with fuel if an electric pump were present. If no
pump, it won't accomplish much, EXCEPT WHEN YOU HAVE AN ELECTRIC CHOKE PULL
OFF. If you have an electric choke pull off, and you turn the ignition on,
and the choke is wired so it comes on with the key, it will open the choke
prematurely.
Assuming that you DON'T HAVE an electric fuel pump, and that your
electric choke is wired from the alternator so that it does not open
prematurely, the starting process should go something like the following.
Insert key into ignition.
Press down slightly on the throttle ONE TIME ONLY. This will set the
choke.
With your foot off the throttle, turn the key to start. Engine should
crank over and start and run on fast idle without stalling. It should start
within 10 - 15 seconds of cranking.
IF NO START, something is not correct.
