Quick Carb question: 73 CG Wagon
Quick Carb question: 73 CG Wagon
Did 73 Colt/Galants come with Solex carbs; or did the wagon i recentlyI bought happen to have an aftermarket one?
Thanks in advance....
Thanks in advance....

Re: Quick Carb question: 73 CG Wagon
I'm 99.9% sure that the Australian version of the cars ran Mikni Solex carbies....I can only imagine that the USA versions ran a similar setup

Re: Quick Carb question: 73 CG Wagon
Mitsubishi built cars ran the early Solex carburettors (easy to spot as they had a rebuildable secondary vacuum actuator), Mikuni/Solex, Aisan - and I have a feeling they used Hitachi carburettors as well.
Re: Quick Carb question: 73 CG Wagon
Thanks guys..... Amazing response time!!
Hey, if I wanted to go Weber (not dual) what model should I go with? Not looking for track days here... Just beefing up the 4g32 slightly...
Feel free to post a link....

Re: Quick Carb question: 73 CG Wagon
Ive seen both 34ADM webbers and 32/36 DGAV webbers being used on 4G32's, i myself am about to rebuild and fit a 34ADM to my 4G32
Re: Quick Carb question: 73 CG Wagon
The 34 ADM is better suited to a bigger capacity engine like a 4G52/54 Astron. The 32/36 DGAV has the same size throttle butterflies as the Solex fitted to Saturn engines but are spaced differently so it'll need an adapter plate to mount it (readily available). You're not going to make big gains from a bolt on carby swap and might need the jetting changed to optimize performance.
Re: Quick Carb question: 73 CG Wagon
Actually you want a 32/36 DFV, not DGV ...... otherwise the throttle opens the wrong way.VGJONO wrote:Ive seen both 34ADM webbers and 32/36 DGAV webbers being used on 4G32's, i myself am about to rebuild and fit a 34ADM to my 4G32
I agree that a 34ADM is probably too big for a stockish 4G32 .... although good on a modified one.
The 32/36 Weber gives a useful power increase on a stock motor (or even a mildly modded one) with good fuel economy ... and the mechanical secondary is a way better system than the vacuum one on the Mikuni. I've got one sitting on the shelf off my old motor .... I can check the jetting for you if you want ?
No it doesn't. The butterflies on the stock Mikuni/Solex are 28mm (primary) and 32mm (secondary).The 32/36 DGAV has the same size throttle butterflies as the Solex fitted to Saturn engines
Re: Quick Carb question: 73 CG Wagon
Sorry, just remembered that was the carby on the Astron II 2.6 (resin body) that shared the same size butterflies as the 32/36 Weber...
Re: Quick Carb question: 73 CG Wagon
If you could check those jetting levels & let me know; please. Only mods ill be doing are air & (in the future) headers; if I can locate some.... Oh, & if I find out my block isn't cracked it'll still need to be bored/honed to +75 over.
Re: Quick Carb question: 73 CG Wagon
Jetting for Weber 32/36DFEV on a lightly modified 4G32 (mild cam, inlet & exhaust ports smoothed & matched to manifolds but not significantly opened up) :
Primary Main Jet 132 = 1.32mm 137
Secondary Main Jet 140 140
Primary Air Corrector 145 165
Secondary Air Corrector 160 160
Primary Idle Jet 60 or 50 (hard to read) 60
Secondary Idle Jet 50 50
I didn't pull the Emulsion Tubes or the Pump Jet, but I suspect they are probably standard.
Stock Emulsions = F66 Primary, F50 Secondary
Note : Numbers in PINK are the "standard" jetting for a 32/36DFEV
In a nutshell, looks like the Primary circuit is jetted down a bit (which would make sense I guess, as the DFEV was standard on a 2L Ford motor) and the Secondary left standard.
Hope this helps !

Re: Quick Carb question: 73 CG Wagon
Immensely!!thank you!
Re: Quick Carb question: 73 CG Wagon
No problem.
Car generally ran very well with this jetting ..... good fuel economy on the highway (at around 95km/h in 4th the secondary wasn't even open) but reasonably good power when needed.
If anything, it probably ran a little bit rich at WOT, but that didn't bother me being a rally car

Re: Quick Carb question: 73 CG Wagon
I'm getting a $100 difference/range. What should I expect to be paying? & are there attachments to the manifold or other stuff that's in(or not) cluded?
Re: Quick Carb question: 73 CG Wagon
No idea in your market what the price should be ! New or used ?
A DFV or DGV is only worth about $50-$75 from a wrecker here (they were a common carb on Ford Escorts, Capris, Cortinas etc). Expect to spend another $50 or so on a gasket kit etc to put through it (any 2nd hand carb will need pulling down & cleaning)
Don't forget you will also need :
- the appropriate adapter plate to mount it on the Saturn manifold (Redline, amongst others, make these)
- rig up a throttle cable
There are no other connections other than an ignition-sourced 12V to the electric choke (I ran mine off the +ve side of the coil) and there is a port on the carb somewhere to hook the vacuum advance for the distibutor to.
Oh yeah .... and don't forget that the Holley 180 / Holley 5200 are basically just a licenced copy of the Weber 32/36 DFV. Might be easier to get hold of over there ?

Re: Quick Carb question: 73 CG Wagon
I didn't even consider going to a pick n pull. New ones are $279 or so on the net. My experience with carbs is nill. You guys happen to know what American models/makes had them or know anyone who's got one for sale? It might be for the best if I go new.... I dunno. I saw an exploded diagram of one on google images & I am certain I don't have the skill to perform a rebuild.
Re: Quick Carb question: 73 CG Wagon
You'll be surprised...
The downdraft Weber is simpler in design than the Mikuni (and should be cheaper to rebuild due to the lack of vacuum actuators). And there is a certain degree of satisfaction in doing something like this yourself (and the potentially huge $$$ you can save). There is no dollar value on learning something useful. Get a manual, and check 'how to' vids on youtube and various car forums for tips - there are tons of resource info available.Rizla215 wrote:It might be for the best if I go new.... I dunno.

Re: Quick Carb question: 73 CG Wagon
Well said. Didn't realize how self-defeating I sounded...
Any specific cars I should be looking for?
