Missing air cleaner parts and connections

1. I try not to throw out original parts if I can help it, they are getting more rare as time goes on. It won't hurt anything to run without EGR unless it just won't stop pinging.

2. You can totally ignore the osac valve. Don't connect any vacuum to it at all.

3. Both of the ports at the bottom left driver-side of the carb are manifold vacuum. Has vacuum at idle and above. The air cleaner, heat/air controls and the choke pull-off use those(the heat/air control taps into the single port at the rear of the intake).

Stuff like the signal for the EGR and it's related vacuum amplifier,the charcoal canister and the ignition advance use ported vacuum since by design those items do not need a vacuum signal at idle.

4. I'd just get an entire used air cleaner from a member here. There were tons of them made and people are probably stumbling over them.

Good Luck!
