BBD final adjustment advice

I was suffering from stall outs mostly when the rpm transitioned after a gear change from first to second... I took the carb apart and tried to adjust the pump arm and the vacuum piston and have it mostly licked....

However... I am feeling a loss of power when my auto. shifts from first to second and from second to third. it seems strong through the RPM range until it shifts up and the RPM's drop and feels like it wants to trip over it's feet. then it'll pick back up and move on.... until the next shift and the RPM's go back down and same thing...

Does this sound like a pump adjustment needs to be done or a Vacuum piston adjustment and if either or both... which way should I adjust it... with the Pump set higher or lower and if it's the vacuum pison.... higher or lower?

I used to smell the finish but not quite taste it.. now I can taste it and wanna eat it.... I'm hungry for this to be finished... my wife has been finished with this project for some time now... [img]images/graemlins/AR15firing.gif[/img]

Re: BBD final adjustment advice

the best adjustment process i've found for the BBD is:

1. remove BBD
2. install mc 2100

saves tons of headaches and frustration.
i got a 2100 off ebay for $20 and a rebuild kit for $12
jeep is running better than ever before.

Ditto on the 2100. Also here's some info that you probably already have. BBD

Re: BBD final adjustment advice

will the 2100 pass smog?

If it doesn't pass smog.... Why?

Is it the visual alteration to my factory equipment?

Will it pass the sniffer portion of the test?

Does it have all the same vacuum line outlets.... what about the stepper motor...?

Re: BBD final adjustment advice

Check out that link that Drury suggested, did wonders for my idle. Also if you haven't already, do the TR Upgrade or TFI Upgrade. Here is a link i saved, but there are many out on the web with the same info - http://keith.cj8.tripod.com/tfi_upgrade.htm

Once i complete these two minor mods my Jeep ran and still runs very well. It used to want to die between shifts and almost no power in 4th. Now if i can squeeze some more power out of it....

Last month i took mine in for it's bi-annual smog. It passed with the TFI Upgrade installed. I did have to put the thermostatic hose and get a new gas cap.
