Possible Carb Probs HELP!!!

Not long bought a clipper for my girlfriend guys, she adores the car but I cannot get it to run right. Please Help! She's in tears. We have changed all engine electrics, had her timed and emissions checked.
She runs fine when started an for the first few minutes runs fine but intermittently, she coughs and splutters under load and then just stops when clutch depressed.
Engine revs freely with no load and is nice and smooth on tickover at 900rpm when coming down from 1100 on auto choke (when not experiencing this problem) Changed plugs, leads,rotor arm,dissy cap, fuel,air & oil & filter. Had tank drained and replaced filler neck, carb cleaned "alledgedly" can anyone please help before I spend any more money, I dont want to have to get rid of her!
Thanks.!!!

what engine has it got?
who did all the work on the setting up? some one who knows old mk1's?
Bert mids too

hmmm does it have the pierberg carb, as they are renouned for being a bit rubbish.
Other than that check all vacuum pipes, ummmm sugestions?

If you have checked vaccuum pies etc, Another common problem is the carburettor flange, these eventually split in areas causing incorrect running as air is escaping.
Easy to tell if its faulty, simply remove the carb leaving the flange on the manifold, then look on the inside of the flange, if you see a bubble or bubbles change the flange, bubbles are a sign of air leaks in the flange.
best wishes bud, hope you get all sorted   :wink:

thanks for the info, the carb is apierburg 2e2, 1.8 8v engine 1990.
any more suggestions welcomed. should i just replace it with a webber manual choke option, if so any idea on best price for supply. looking at post someone suggested a small filter inder the fuel pump but not sure if this has been changed recently as it had a new fuel pump.thanks for your help.

Hi guys thanks for all your help, Clipper is now thundering along now, tank cleaned and filler neck replaced done 150 miles now on all roads and conditions, and not missed a beat on original Pierburg. Can get to work on everything else now shes reliable.
Can someone enlighten me if they have experienced problems with the interior heater system? Mine is constantly on hot! The slider and cable is working fine it seems to the hose in the engine bay! Any Ideas guys? Also fan switch is not working on any speed but to be honest havn't checked the fuses yet.
Cheers, Bigelsy!!!!

Probably a leaking heater control valve - the cable goes from the dash out to the engine bay, to a valve on the heater hose (located near the brake servo). The valve gets worn with age, and leaks hot water into the heater matrix, even when the heater control is set to cold. New ones are availble in all the usual suppliers…

Thanks Steve! suspected as much just wanted to check with someone first before i spent any money on bits! Cheers Mate!!
