Vixen, What carburettor should I have?

[phazed]

I'm just trying to sort out the carburation on my 1970 series 2 Ford engined Vixen

I have a Weber 32DGV fitted.

I have no idea whether this is the correct carburettor for this car.

Is there a standard carburettor that was fitted? If not please let me know what I should have?

As the car is not running correctly at the moment, (carburation) this may be the opportunity to fit twin carburettors.

The engine has been totally rebuilt and runs very smoothly, starts effortlessly and is very quiet.

The problem I have is that it runs nicely on what I assume is the first choke but when you increased the throttle its starts missing and sort of cutting out.

As far as I am aware it is probably a standard period engine. It has a four into two into one exhaust manifold but the remainder of the specification is a mystery and I will probably never know exactly what it is.

It may be a better idea to stick with the correct twin choke carburettor but ensure that it is jetted correctly.

Are you aware of what I should have fitted jet wise to my carburator?

Carb 32DGV 7a. 069639

Accelerator pump works ok.
2 jets in base of float bowl are No142
Air correction jets in the top of the body are 125 & 170.
Choke size is 1 1/4"

A different carburettor to mine, I wonder what the difference is?

Interesting, does that mean it is the correct carburettor for this car?

I wonder why the code stamped on it just says 32DGV?

Do you know what jetting I should be running?

My options are open at the moment Andrew.

I will hopefully get this to run properly as it is and then consider what else to do next winter.

I will have enough on my hands rebuilding the 5.5 and progressing that in the next few months.

Guys. Just finished a family thing and have come back to all these replies! Thanks.

First, I will go over the carb thoroughly and hopefully get the car running better with whatever I find wrong with it.

Secondly, from the info given, the 32/36 carb should give a little more performance?

As for the twin 40s, once I have shaken down this little car I will be thinking about its future.

I've a lot to do over the next couple of months on my Chim, (full engine rebuild, box refurb etc, etc) do will squeeze in the carb works sooner than later.

Gonna have a little look at the links now.

Thanks again.

1964 Austin 1100, my first ever car, loved it only 'cause it was my first!

Just found this, seems very useful.

Just browsing on the silly and found this.

Is this a sensible upgrade before I start messing around with my old carburettor, (cost aside)?

If so, this seems to be the correct model I believe?

[phazed]

As for the condition of the engine. It was fully rebuilt by power crazy less than 2000 miles ago and had a rebore, new rings, new camshaft and a reconditioned head and valves amongst other things with the engine given a full going over .
These works were carried out by the previous owner.

So given the above, I'm sure that it is a carburettor problem. Of course I will be checking the ignition timing to make sure that all available horses are utilised.

While on the subject, can someone let me know what the ignition timing is on this engine?

Yes.

BUT! I have heard stories that these carbs are now mass produced in foreign lands and sometimes have wrong jets installed and swarf inside them I have seen pics of similar supplied which needed a full strip, clean and re-build before they would work effectively.
They are as simple a carb as you can get so I would spend £18 first and take the top off the old one….Chances are it is just a diaphragm or something simple.

Dishwasher is nearly as good as an ultrasonic cleaner ;-)

Will do. The carburettor was stripped this morning into its components.

I will chuck it in the dishwasher tomorrow while my wife is at work, ha ha.

You are quite right about the dishwasher, I did various parts from my V8 a couple of weeks ago and they came out fantastic.

Some I prepared earlier.

Just so you all know the car was originally fitted with a Lotus Twin Cam from factory. The engine in the car now is from as already said Capri or Cortina GT, been allotted to the car many many years ago.

Well there's your problem and solution in one, Peter. You just HAVE to return it to factory spec... start saving!
And yes, it will have to have a pair of sidedrafts... Webers or Dellortos?

Thanks for the confirmation Perry, it is slightly confusing cross referencing Ford to TVR and given the age, nothing is concrete regarding the engine spec I guess.

Rik, it would be great to fit a twin cam in there but the chances of bagging the correct motor is probably slim, (and expensive!).

Talk to Steve @ Powercrazy on 07979231317 he is very approachable and he rebuilt the engine and fitted the jetting you have in the carb. ran perfectly last time I drove it, to be fair that was a year ago. Neil has already suggested a couple of courses to remedy already.

Good idea, thanks Perry.

You bugger, stop it!

A twin cam is on the back burner.

First I would like to sort out a bit of history of the car, any ideas where I could start?

As for the carburation .

I removed the carburettor, stripped it down and chucked it in the dishwasher on a hot wash.

Assembled with an overhaul Kit, increased the main jet size by five, assembled and fitted to car.

Now, no stuttering on the second choke and car runs pretty well! Thank goodness for dishwashers
