my old cortina, I BOUGHT HER A WEEK AGO RUNNING NOISILY (CAM NOISE) AND (SORRY CAPS!!) and was told by dodgy bloke it's got slight cam noise and needs the carb sorting...........

friend of mine is mechanic and old enough to remember the old girl.......

he has done valve clearances and the cam is spotless.... also put new fuel pump on her, new battery, checked all obvious things.......
everything looks good and well maintained....... carb been taken to bits and cant see anything obviously wrong in there, all looks clean and no obvious blockages... no water in fuel and not old fuel...... does not smoke and now runs quiet and sounds sweet....

car in vgc generally, waxoyled to within an inch of her life, done 90,000 from new and been regularly serviced (got receipts), been running on road til last october when tax ran out, done 500 miles since last service in april '11.........

She often doesn't want to start, when she does she normally cuts out (hence new fuel pump as thought was fuel problem) if she does run and tick over then when revved she starts to run lumpy and as soon as you take your foot off throttle she dies.....

she does not misfire, backfire or run on and is running on all four cylinders....... HELP.........

anyone any ideas why she won't run???? You can't drive her as she just dies...

HELP please!

what carb you got on it? if its pierburg, bin it and fit twin webers, same if its a ford vv.

have you got it up to temp and tried it?

have you fitted new points, condenser, rotor arm, and dizzy cap? these are always worthwhile
(its the first time i've suggested this in a year/nearly 7k posts!!!)

thanks, has a ford vv on it as from factory!!! all serviceable normal bits are good and new!! carb has been taken apart and checked- nothing obvious to find... you still reckon bin it???

[GingerTom]

My Cortina did that and it turned out to be the HT leads.   Just a suggestion.

once you have some webers on it you won't ever look back, as ginger tom said, check ht leads as well, although to be honest it might be worth getting some new ones as a matter of course.

The vv was a decent enough carb when nice and new but quite temperamental with old age, did you check the diaphragm for splits as this is a common failing and causes poor running, other problems with it are worn needles and auto choke faults.
I'm assuming the basics have been done on the engine like timing checked, points replaced and correctly gapped, condenser replaced, plugs checked etc?

i see no comment with ref the pierturd carb...

i had to start my vv on my sierra with a capful of petrol as the autochoke had failed for ages, then i lost the cap so it was jerrycan, eventually i ended up fitting the twinpot webers and never looked back... then i fitted a 2.0 tina lump in it

anyone know what replaces the original caerb on the 1979 mark iv estate cortina.... it's a 2 bolt fixing to the manifold and has a manual choke....... cant find anything...... HELP PLEASE...

[bobogee1]

I put a 32/36 dgav on the one i had because i got fed up of the same problem your having.Was much better and faster as well.I used the inlet manifold from an rs2000 and had the carb rejetted.

[siruncle]

this is the sort of thing you want, but the seller doesn't mention the engine size its off so be worth asking before bidding. if its off a 1.6 it should be bolt on, hose up and fire it up, I'm pretty sure the same carb fits both the 1.6 and the 2.0 and if its off a 2.0 someone with a little knowledge of tweaking the setup should be able to get it going a treat. http://www.ebay.co.u...9#ht_500wt_1287
