The other one (pointing straight out to the right side of the car) is the power jet, which feeds additional fuel at high throttle/high rpm. The three wires could each go up to fuse #12 individually, but that would be very inconvenient. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX.

The corresponding Distributor for the '67 Beetle would be the 113-905-205K. Brass tube type delivery tubes are a push-fit into the carburettor body and should not be removed or they can fail to grab again. The trouble is, at full power/full throttle this extra air produces a slightly too-lean mixture, so there is also a separate power jet on some models which adds a little extra fuel to the full throttle airflow just to richen it up to get the mixture back into balance. For a 1600 KG with 34PICT/3 and vacuum distributor, I'd suggest a 60 or 65 idle jet (a 55 idle jet is used for the bug but the heavy bodied KGs and buses used larger idle jets), 127.5 main, 80 or 100 air correction jet (80 makes it run a little richer in the mid range) and a 65 power jet.

I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. The power jet is needed to correct a tendency for the air correction jet to work TOO well at max airflow - it leans the mixture off too much and the power jet corrects this. So, I let it warm up, and set the timing to 32 degrees full advance.
