Black-Box Removal/ Carb Tech

[FlatBlackDime]

Where did all of A20A1's posts/ diagrams for vacuum removal go?!

I'm in the process of putting my 3g back together and want to make sure im removing the right stuff...

I've been following a printout of A20A1's stage 1 guide....Removed all the little metal vac piping, black box, egr stuff...I have no A/C, so therefore i wont have the A/C boost valve?

For reference I ported the new head thats on the car and its got a delta 272 cam in it...

yeah, it is....sorry for the noob post


Swear I'll spend longer with the search button next time :D

[A20A1]

the images throughout the board were dislocated... so you'll need to wait a while.

[FlatBlackDime]

you wouldn't happen to have them would you? I can get them hosted...


So im going to basically take everything off the carb/ manifold, convert to mechanical secondary, and retain just the air correction stuff (A.B,C box)?

On another note...to retain choke functionality what has to be hooked up? just the two lines off the choke actuator?

Ok, got the car running...Runs really well now, idles great, isnt any more rich than it was before...But one last question

What should I with vacuum advance? I set the car to 4deg advance per the FSM, and then hooked up both the advance ports on the distributor to the vacuum port on the back of the manifold, this immediatly changed the timing...Doesn't seem right...Somehow the vacuum seen by the disributor should be switched, right?

?

You can only hook up one if you want. Or hook #25 thru a thermovalve.

That vacuum diagram was to keep choke. I dunno if it works completely because I never kept choke, the vacuum removal was ment to remove all vacuum lines and just tune the carb by redrilling jets or increasng the venturi diameter.

I successfully kept the choke by using the thermovalve at the back of the manifold per the first diagram...So that part works for sure

So you're saying i should tap off of #18 for the vac-advance?

Thank you very much for providing these diagrams, extremely well laid-out and extremely informative...

[A20A1]

Well there is a second thermovalve next to the one that is used by the choke... that thermovalve is for the #25 vacuum advance.
I sort of erased the thermovalve in the image.
