What are these on a 1983 RX7 carburetor
 

Hello gang,
I am prepping a 1983 RX7 as a 24 hrs of Lemons car and to the point of cleaning up the carburetor. I have another carburetor as an example that had be prepped by someone that is reported to know what they are doing and everything has made sense but these two tubes running from outside of the carb to each primary venturi. I have searched the web but have not found out what these are for. i was thinking oil injection but I have not found any diagrams showing oil feed lines going to these. In fact nothing is shown going to these.
I know they connect through because i can blow carburetor cleaner through them

the Metering lines go there

Metering lines are what I called the oil injection lines, correct?
thank you

yep!

If you ain’t gonna install the oil lines make sure you premix your gas or your apex seals are gonna go dry

Thank you
