Turn the Pilot screw out a bit. 1 to 1 1/2 turns should do it. You will likely have to drill out the brass cap that covers it.
It is on the front side of the bowl. It will also start much better.
make changes of 1/4 to 1/2 turn at a time.
It's a good idea to screw it all the way in while counting turns so you have a baseline to return to if you get confused or loose count.
p.s. Black text is hard to read.
