Vixen Carb

[jpa]

Hi

Have finally fired up the engine on the Vixen today after 8 years (plus maybe) of hibernation. I must say it ran quite sweetly considering, despite the slightly loud exhaust.


However, it has what I believe is a standard 1600 x-flow (although it may have been 'worked over a bit, who knows) but I discovered that it has a non standard carb.

I believe the standard carb for capri GT engine should be a weber DFM or DFE, although the vixen website lists the carb as a DGV. My car actually has a 32 DFV which as far I can find out, is standard for a later 2.0 capri engine.

Does anyone know if the DFV carb is suitable for the engine or will this be over-fuelling the car? If it is OK, how can I check if it is jetted correctly for this size of engine? Or, should I try and get hold of a DGV or DFM?

Any advice appreciated.

Cheers
Paul.

Hi Paul,

I can't help with your question but it sounds as if today was a bit of a special day

The problem with switching carbs from the DFM to the DGV or webber replacement listed for the replacement to the DFM is the change to the throttle linkage and manifold. The DFM was discontinued after the Cortina MK2. webber list a replacement which is basically the direct twin choke Escort MK2 unit. To fit one though you need the Escort inlet manifold which has 2 threaded bosses for the throttle linkage bracket which pivots a different way (you also need the linkage bracket). You also from memory need a couple of BSP blanking plugs because the new manifold has more vacuum take offs. You also end up using a Cortina MK4 throttle cable which has the correct end for the carb

Its all available new to buy, you just cant change carb alone

The DGV is the same carb for 1.6 OHV and 1.6 / 2.0 OHC engines so I wouldn't worry too much. you just order the correct jet and venturi sizes for your car when ordering from webber As long as the carb is jetted correctly then if it works why worry.

Look for mixture. You will have a very rich mixture if your carb is straight off a 2.0 OHC. look on the carb for part number and ring weber. They will tell you if it is correct carb.

I may have some old twin choke stuff knocking around in the garage. I will have a look tonight.

Thanks Guys.

I was going to check the mixture etc once I get it running for a while (dynamo is not playing ball at mo!).

So I assume that a DFV as mine is labelled is basically the same as the DGV.

I will get the colourtune on and see if I can get a good mixture, if not I will look at changing the jet etc.
