Capri Carb Advice?

The-Ry-Man06

Im really need to do something about the standard 1.6 carb on the mk3 capri. I was looking at getting a Webber DOCE im not sure of the correct barrel size but people have been recommending i just overhaul the standard or get it proffessionaly restored from someone like McNamaras on William st. Any thoughts?

The Capri will have a Weber 32/36 DGAV on it, and the options are.

1. Rebuild/re-jet the existing Weber. That's the easiest and cheapest. If you've not changed cam or got head work, leave the standard jetting and get it rebuilt (eg McNamara's). FYI, the 32/36 DGAV is the carb that's fitted to the 2.0 RS Pinto's as well.

2. Get a 38DGAS of a 3.0 Essex V6 (Capri, Granada etc). If you've not got a lot of engine work (eg Head, cam, etc) I wouldn't bother as it'll probably overfuel and a rolling road session would be needed to get it jetted right. It'll bolt onto the manifold though.

3. The DCOE route (they are called DCOE, not DOCE) These carbs have different Barrel sizes (40mm, 45mm, 48mm & 50mm) and are commonly known by their barrel size (eg twin 40's for the 40mm). If you are going that route, you can go with two DCOE Carbs on a new manifold, or if you can find a (rare) lynx Manifold, you can have one DCOE. These carbs are commonly fitted to race engines as they work extremely well at full throttle and have one choke per cylinder. The downsides is that you'll have to get manifold, Fuel pressure regulator, fuel pump (you can;t use the mechanical pump as it's got a rising pressure as revs rise) and rolling road session. They'll also drink fuel, they don't like been driven at slow engine speeds and on a standard engine, they're a waste of time.

I've a 1300 crossflow'd Mk2 Escort at home with some work done to it (ported/polished big valve head, custom Piper fast road cam, ARP bolts, balanced/polished crank & rods, high compression pistons etc) and I'm running a rejetted 32/36 DGV (manual choke version of DGAV) and it's running sweet. If I were you, I'd send the current Weber off to be re-built. If you look at the base of the carb, there should be a model number, as well as a little plate to show you the carb details.

I assume you've got one of these carbs, and not a horrid motorcraft one. I'm fairly sure that it's a Weber on them.



If you've got a Motorcraft one, I'd get on to Weber UK and get an upgrade kit for it pronto.

I agree with Ian.
Some of the 1600's had that VV carb with the diaphragm on the side if you have one of those carbs throw it away and go for the 32/36- the manifold would need to be changed for this.
I think the 38 would be too much for the 1600.

Forget the DCOE for a road car.

Brilliant advise cheers lads. I presumed i had a VV carb as my friends mk3 1.6 laser also had a VV but ill take it off a check. I presume a 32/36 DGAV would be easy enough to find off an old 2.0 pinto? If i went that route should i just send the 32/36 DGAV to somewhere like McNamaras to be refurbished and rejetted? Any idea what sort of cost id be looking at?

What about a 34ich as ive been told the conversion kit is easily available and gives relatively the same performance? Aso isnt the inlet on the 2.0l carb oval while it circular on the 1.6?

btw just checked the carb its a VV, diaphram and all (****e as ever, sounds like its on its last legs)

Have a look at this

http://www.webcon.co.uk/Downloads/2008%20Webcon%20replacement%20carburettor%20kits.pdf


It's from Webcon in the UK, and it's a list of Weber upgrade kits.

Have a chat with McNamara's. They are a Weber Agent and I've only heard good things about them (and dealt with once and was very happy)

well i got on to McNamaras and they quoted 650euro for a 32/36 DGAV with full conversion kit (inc. inlet manifold and pancake air filter) and fitting which is 220euro of the 650. Seems ridiculos i didnt think it was so expensive but i have very little other choice. Any thoughts?

thats very expensive. have you tried to get a second hand unit and/or fit it yourself?

The manifold is GB£150 plus delivery from Burton Power for a new one (I just checked).

There are bound to be pinto's dumped with the manifold still attached - Try some rally heads as the Pinto is still popular for rallying

I would avoid McNamXXXX like the plague. Poor customer service, idiots and they overcharge. If you cant do it yourself get a decent mechanic to do it, its not rocket science, or try Aidan Bermingham.
