Correct 3x2 (tripower) throttle spring setup with A/C

Re: Correct 3x2 (tripower) throttle spring setup with A/C

Jay - I'd call Paragon and ask if they still have the older PDF catalogs that they can email to you.

Pat

Pat, I'll do that if the following picture is different than the one John is referring to.

The older Paragon catalogs used to have a picture catalog that showed how the bracket and spring mounted. It is no longer in the current one. Do you have any old catalogs available to look at? It's on page 44 of the v28 2003 catalog.

John, Does this picture match the one from V.28? The oldest catalog I have is V30 from 2005 which has the following picture of the tripower linkage.



Thanks,

Jay

My new spring is from Paragon, it is the same as the original. I looked at a lot of original cars, the AIM and pictures in shop manuals and this setup seems to be as original.
I don't know where they came up with that bracket as I have never seen it in use on a 3x2???

Jamie,

Not doubting what you are saying but I just went out and tried your suggestion and hooked up the spring where is seems logical (between the hole in throttle cable bracket and throttle arm) I am getting interference near WOT between the spring and throttle arm that I doubt the GM engineers would have approved of. It would also have lead to wear pattern on the back side of the throttle arm and more critically to the return spring which could cause the spring to fail which might cause some excitement to say the least.

Jay,
Looks like you might have the wrong throttle arm to me on your carb.
I don't have that big round part that is rubbing on my arm (look at my pic).
Might be off of a Mopar Six-Pac or something else.
Check your throttle arm configuration against others.

I was thinking that the carb may be part of the problem since it is a service replacement. The angle of the other picture makes it look a lot different that it really is. Here is a better shot of the arm configuration.

Does this look like yours?

Attached is the picture from the old Paragon catalog (they still use the same illustration) you show. I don't have a 69 tri-power so I can't say if it is actually correct or not.

John,

Thanks for the picture but I am more convinced than ever that the combination Paragon is showing will never work correctly. Either the spring is too short or the bracket is too short but the combination of the two parts definitely doesn't work and couldn't have been the way GM designed it.

For the time being, I am using the paragon bracket to keep the spring from interfering with the throttle arm and I went to the hardware store and bought a longer spring that has more stretch in it and that seems to be working OK.

Thanks to everyone for their thoughts and efforts on this one.

Regards,

Jay
