the gauge will fluctuate quite a bit but I don't see how your gonna synch them with only 1 tube at a time.
you can get one made for a bike for under 100.00 so why not just go that route & save yourself a lot of hassle.

maybe someone in your area already has one you could use? where are you located?

 

I have a manometer/ you set the throttle bodie 3 with a vacuum gauge to spec then you sync the 1,2 and 4 too 3 with the manometer.....and if the vacuum gauge was flutering a little I could read it but I do believe I said it fluter's VIOLENTLY so I can not read it.......

 

then I guess I can't help you.

I just use a vacuum (mercury) gauge that's made specifically for this purpose & I don't have any of your VIOLENT problems.

 

You will always get the violent flutter if there is no damper fitted in the vacuum pipe.

You can make your own damper by cutting approx 4 inches off the end of the vacuum hose then rejoining the two pieces of hose by using a piece of smaller diameter hose inside the vacuum hose.

Hope this makes sense!

 

Yep perfect sense, thanks neenaw

Ok I'm assuming your bent cuz I capted VIOLENT (i could be wrong) I had no intention other then violent as in I can't read it.....also this mercury filled gauge your taking about is called a manometer and before you use the manometer you need a vacuum pressure gauge to set the number 3 throttle bodie ,then you use the manometer witch is hooked up to all 4 vacuum lines and set them all to the number 3 throttle body.....I am quoting straight out of the repair manual and talking with others on here in cluding Neenaw it has been concluded that I need to restrict the air more then it is now...but seriously I appericate you trying to help me I truely do.....and like I said my intentions were good

 

I recently made a manometer. I found at the local autoparts store a "Universal Vacuum Adapter". This connector allows you to connect vacuum lines of different diameter together which may work as a damper because it tapers at the ends. Hope this makes sense.

 

I now exactly what you are talking about, I almost bought some but they didn't have 4 they only had 2.......thanks shawn

 

no problem here!

I don't bother calibrating the #3 & then going from there, I just adjust them so that they are all the same. works for me. :dunno

 

He had to do that because me messed around with #3 adjustment. So he was trying to get it back to factory specs.

I agree... normally you just need to set them so they are all the same (which can only be done correctly with all 4 TBs hooked up together.

 

now I understand! thank you!

OP, sorry I'm a dick sometimes.
