Sol-Vac - What is it Do I really Need it???

I was looking through the posts for carb idle help for my 88YJ BBD. I found info on setting the idle with the Sol-Vac. I DONT HAVE ONE. Maybe this is my problem?? Will I need this if I upgrade to a Weber? Apparently a missing Sol-Vac means I have vacume lines floating some where or mis-connected...This could answer many questions

The SolVac was a idle speed control device. You won't need it with a Weber. Do a search on ORC for "258 primer". It has all your answers.

1. You've got good information above,
2. You can use the Sol-Vac to bump the idle up,
3. If you're using a winch...
4. There's a use for everything!

I appreciate the info. My question now is do I have to have it to get my BBD to function properly?

Re: Sol-Vac - What is it Do I really Need it???

The Sol-Vac serves a couple of different functions - it raises the idle when you turn your defrost/ac on, or when the engine experiences some other large electrical load. it serves the purpose of a dashpot to hold the throttle plate open for a second after let off the gas all of the sudden... also it raises your idle speed upon start up and let's it down slowly.

So, while it's not essential as far as correct operation, it is fairly important, yes. In the end, there is really no correct carter BBD operation. It's a POS that should get chucked as soon as possible.

On a different note, this has to be the 10th friggin bbd related question in the past week or two. People, come on, PLEASE START SEARCHING. I am rarely the board member who slams people for asking questions that are constantly asked, but please, at least try and search for "bbd" or "Carter" or "Sol-vac"....

Re: Sol-Vac - What is it Do I really Need it???

1. If you haven't visited "What is all ths Stuff?" yet, then I'd advise it.
2. When you read it and digest it, you'll be forwarned whtat you're up against.
3. The way you get the BBD system to work is a mystery known to few,
4. And there's another question,
5. How long will it stay that way once you do get it fixed.
6. I spent over $400 chasing BBD problems when I first got my CJ.
7. Now that's within $100 of the MegaSquirt DYI Install.
8. When you read though the varied BBD related posts,
9. They most ALWAYS point to replacement,
10. Unless you have Emission issues,
11. I admit... it's still a mystery to me,
12. EFI was far easier to understand.
13. and with todays knowledge and parts,
14. Far less expensive to install and maintain,
15. But if you're intent on fixing that BBD,
16. The contact Brendan McGuirl via PM or Email.
17. He seems to know what he's doing on the BBD,
18. As does Stilllearnign6
19. Both these guys know a whole lot more about the system than I do...
21. May I suggest:
a. This, and
b. This.
22. Read, Re-read, Review and Re-read again BEFORE you touch anything,
23. Fix one item at a time and confirm it's fixed.
24. The BBD can run you ragged in no time.
25. As for me, I take my hat off to anyone brave enough to:
a. Delve in to the BBD system,
b. Make it work,
c. Understand it and
d. Maintain it.
