I have a new project - and it has 4 wheels!!!

If the needle valve is grooved it could be flooding, hence the poor fuel consumption and the mixture screw not doing much, especially if thats been screwed in too tight and grooved too. With the engine running, the screw should stall the engine if you wind it in enough. Jets are so small that they you cant really tell if their worn unless you compare them to new ones. Sounds like its gubbed.
Burlen fuel systems and carburettor hospital are good for parts for classic stuff, and for info, you might find the carb is a specific set up for the CF against other GM stuff.
I used to have some CF parts but i`m sure they got binned in a clearout years ago but i`ll have a look if I have anything your welcome to it.

EDIT: Infact, i`ve still got my Burlen catalogues, if you give me the details of the van i`ll have a look and tell you whats compatible and see if theres part numbers or jet size info etc.

Cool, that would be great. I have a complete spare carb which I might rip parts off when I collect it (its still with the seller as I ran out of room there were so many spares that came with the van).

The van is a 1971 CF, short wheel base, single wheel per hub on the rear. The engine is a 1975cc petrol with 4 speed manual box. As said, it's running the original Zenith carb (36IV - not the 36IVE), and a Delco dizzy (also original I think). 60k miles on the clock. If you can verify what other vehicles have the same carb that would be very helpful. The one I have my eye on is from a Vauxhall Viva / Victor 69-70. I know jetting will be different but I have the spec for the CF so I can order new jets.

According to this carb book, the 1975cc CF was only from 1969-70 (another book says 69-72 tho), and has a 361V carb, which also fits :

1600 Viva HC 1971-72
1600 Viva HC and Firenza 1970-71
1600 Viva and Victor 1969-70, and 1970 on
1600 Victor 34 series,
1760 Viva and Victor FE 1972-73
2000 Victor FD35 1967-69

They all have different carb ref numbers, but they also all use the same needle valve ( B17258 ), floats, gaskets etc.
Looks like the carb you have your eye on would be a perfect match

Who did you insure your van with in the end Phil? We're trying tio get decent quotes for our Mk2 Transit camper at the moment and can't get anything below £500 fully comp

Cheers,

£500! Bloody hell Paul - how can it cost that much? My VW is less than half of that for full comp.

I went with RH insurance. Cheepest by a long way at £113 fully comp! you ned to call their specialist vehicle section, not the camper van section. The cover isn't as good in the way of personal belongings etc but it has windscreen and the usual stuff more common with a car policy.

Thats who my classic is insured with too.

Right, I've ordered a new carb from the Viva / Victor '68-70. also got a NOS rebuild kit for £10 but no new jets with that, so I'll give it a go and see what happens with the economy. I'm assuming I'll have to swap the jets over but I'll just take a look when it arrives and compare with the stock spec on the Bedford.
