I question how the carb is suppose to vent the vapors, if you cap the outside vent off? From my understanding, without that vent, vapors will enter the carb bore and create difficult hot-starts. Perhaps Mike can confirm.

Without a canister, I think I'd attach a short section of hose with a vent cap, similar to a transmission or diff vent.

The BBD has a rear center port for the PCV which comes from the front baffled hole in the valve cover. It has a corner port for the choke pull off as all of us don't seem to know..

Edit: including me it would seem.... Just looked at my spare and you are correct on that one.

The EGR also is supposed to route through a thermostat in the air filter so it doesn't open if you have -40 temps sucking in there which would really cause a bog.

Everyone I have (have had 4 now and access to 2 more) all have the PCV on the right and the small choke pull off in the center.

Yes on the EGR normally but it sounded like he didn't have the stock setup anymore so I was addressing what it sounded like he did have and wanted to keep.
