I need to rebuild the carb on my 74, can someone let me know if this kit will work.

Ant tips on rebuilding this carb, I've never done one before, but I am mechanically handy.

Yes and No.

 

Since so many of the original Solex carbs have been replaced with Webers, make sure what carb  you intend to rebuild. If your carb is original, than it does appear that the "kit" is for your vehicle. You neglected to mention whether your model is automatic or manual.    I suspect there are some slight variations between automatic transmission equipped carbs and manual versions but hopefully the differences are minor so that rebuilding is not affected by the kit.  Looking at the application chart is hit or miss considering it also fits a 2002 turbo, which, last time I checked, may have been injected.

 

The Solex carb is a little more involved that the Weber in terms of rebuilding.  You did not explain why you are rebuilding the carb and it is probably beyond your question, but given your limited carb rebuilding experience, if you can diagnose the problem to something specific with the carb, it might be easier for you to tackle the carb in stages.  By analogy, most mechanically handy folks can replace a watch battery but replacing a main spring is not necessarily the same thing.  If you intend to replace worn or torn gaskets, a needle and seat, and a leaky float, I would give it a go.  Disassembling every single component can be a little more complicated.  Most things are easy when you know how to do them.    

 

Recommend that you take photos as a reference.  I suppose that if you encounter problems there are FAQ'ers who may offer a helping hand or, if you are eligible, a beer.

Not sure about the kit, but most people will tell you not to bother to rebuild the Solex and just get a Weber; unless you want to keep it original. I still use my Solex, but plan to get Weber 32/36 to replace it.

It is a 74 automatic, I want to keep it as original as possible, it just runs poorly right now. I thought I would give this a shot.

"Poorly" doesn't offer much to go on.  Today" I don't feel so good" can mean a lot of things too.

 

Poor idle?  Poor mid range?  Poor fuel economy?

 

All of these things can be carb related.  They can also be related to ignition and engine wear. The newest carb and distributor will never make up for poor compression, except in the looks department.

 

Again, I would not dissuade you from rebuilding this or any carb.  You have to start somewhere.  As a child of a much earlier decade, sometimes disassembling things is the way many of us learned.  Tuition in the school of hard knocks just seems to be a little more expensive now a days.

You car was originally equipped with the Solex 32-32 DIDTA.  The kit advertised states it is for a SOLEX 32-35 DIDTA.  Might want to do some further research.....

yeah, but the interchange part number says it works on the 32/32

Based on the pictures it looks like really old NOS, old gaskets can get brittle just sitting on a shelf for 30+ years, you may want to ask the seller when this was manufactured. Other sources list new kits for only a few dollars more so you may want to shop around.

Good observation.   It's been a long time and I seem to recall the 32-35 DIDTA as being an upgrade (when available) instead of the Weber.  Curious thing, a certain entity mistook the 32-35 as stock which probably led to more confusion.  http://arb.ca.gov/msprog/aftermkt/devices/eo/D-133-6.pdf   Still, aside from the base gaskets being slightly larger to accommodate the +3mm secondary bore diameter, I suspect the kit differences are minor.

Two more things on the Solexes...a common failure point on the 32-32 DIDTA carbs was the vacuum diaphragm that opens the second barrel.  Check to see if (1) the kit includes the diaphragm and (2) if not, is it available.  It's kinda crucial to the carb's proper operation and if it's NLA you might as well switch to the Weber, which has a mechanical link to the second barrel.

 

Also, the automatic choke mechanism wears on those Solexes, especially the rachet that governs the fast idle when the choke is on.  That part was NLA back in the late 70s (when I switched to a Weber) so if you have no fast idle when the choke is on, you either have to make the part, or...get a Weber.
