Marshall -
First off, I was finally able to get your carb installed and the desmog completed today. All in one day with ZERO hiccups. You, my friend, have brought much joy to a young's boy heart! Sweet Glorious Day!!
But,
Surprisingly, I can't seem to locate the answer to a couple vacuum hose routing questions and thought I would post them here for anyone else with the same questions/concerns. I used the "How to Desmog" pdf found somewhere here on the forum, but I realized a few pages in that it pertains to keeping the OEM carb - so I modified accordingly. I have a (now) fully desmogged 08/1985 FJ60 2F with 127K miles and live at 4,000 feet in Hell Paso, TX.
I retained the AC Idle up, swapped out Idle Solenoid, and deleted the Choke Breaker and Choke Opener. Retained BVSV(1), both VTVs, HIC, HAI, PCV Valve, and Gas Filter. Pulled and plugged BVSV(2), air rail and all the other stuff, yada, yada, yada.
With that historical evidence in mind:
1) On the side of the distributer, I have the Vacuum Advance Port capped off since your carb doesn't have the Advance Port. I then ran a new hose from the HAC Advance Port to the HAC port (d or lower of the 4 nipples) with a "T" fitting enroute on the driver fender. Off the "T" fitting is a hose that runs to one nipple of Gas Filter on Intake Manifold.
2) The second nipple on Gas Filter goes to VCV port (S) on passenger side. The third nipple is capped off.
3) All top ports (a - c) on the HAC are capped off since your carb has no fittings to run these lines to either - which pretty much tells me that's it's worthless now and I can just pull and toss it. This is where I have a bit of confusion - {Question 1} Should I just toss the HAC and cap off the HAC Advance Port on the distributor as well, thus rendering it completely useless too?
4) If "yes" then what about the Gas Filter? {Question 2} Should I just cap those nipples (I like to say nipples) off as well or even just pull and plug the hole? Ha!
5) Lastly, {Question 3} what are your recommendations for the default mixture screw at 4,000 feet? I currently have it set at 2 turns out from all the way in according to the specs in the FSM.
Now, with the way I have it currently setup, the old girl runs like never before - VERY smooth acceleration and power all the up to each shift point. I'm mainly concerned with whether or not I'm actually still getting any benefit from the HAC and what should I expect to see when I start going up in altitude? And the mixture - where should I set it at?
Thanks!
