I start mine this way;
1st start of the day, full choke, ignition on, flip a few times and it should pop and cut out.
(It won't run on full choke)
When you have it at that point, take the choke off completely and it should start with one or two hard flips.
If you re-start it during the day it should start without the choke, but if it doesn't want to play ball go back to step 1

When you flip a gasser don't muck around, use a good amount of force and follow through with your arm so you get your hand out of the way.
A lot of people use a heavy leather glove.
