The shooter (squirter)should have a two digit stamping on it. The stamping would be on the side that is facing the middle of the carb.
(28=.028", etc.)
I have a carb that both squirters came from QF with no stamping which means .031" to them.

Note: the larger the squirter the "quicker" it will deliver the fuel and visa-versa.

Do you have any extra squirters to try?
