How do I identify a high altitude jet? 1999 Mercury 15 2 stroke

[Mgray1982]

Just wondering if there is any way I can identify what jet I have installed? If I look in the carb barrel, all I can see is a little brass tube thing running down the middle.

Thanks

Look on the bottom of the carb and there should be a plug. Take it off and the jet is inside. If it hasn't been changed it should be a .072.
