I'm not exactly sure this will work for you,but it did work for me!
I used the principal as the same way you adjust the jet screws on a carburator of an old car!!!
Turn them both back to the starting position(just when they won't turn no more),then very slowly just turn each one a TINY,TINY,TINY bit,then stop and try to get it to run,after you turn them a tiny bit,then try it again,untill you finaly get it to run. If this doesn't work,you will have to find another solution!
Good luck and may GOD BLESS! MR> NEIL WILLIAMS
