1300 cross flow problems

[rangerstuart]

Hi been having problems with a 1300 mk 2 escort engine running rough and not accelerating beyond 35MPH, fitted a new fuel filter and ticked over brilliant sounded great, old filter was Black......Took the car out for a run yesturday and still didnt feel right, tick over was fine but as soon as it drove about 1/2 a mile it lost power then sounded as if it wasnt firing on all cylinders very very lumpy, so i thought it may well be a bit of rubbish in carb maybe, so took it a bit further where it eventually just died on me, no power at all and would not even rev. towed the jeep home and going to have a look tonight. The only things i checked last night was the simple ones first distributor cap, and rotor arm which are as new, HT leads which are on fine, however from past experience even new ones fail.
Thought i would take carb off and give a jet through just in case its blocked. also give the air filter a good clean/wash.
Oil is fine and water is fine, just wondering maybe piston seals but no knocking noise.
Hoping its just the carb that needs cleaning.
Its a 1300 crossflow engine from a Mk2 escort. If its not the carb and before i go stripping it down further has anyone had anything similar?
cheers

Had something similar years ago on a Fiesta that would not rev well. Turned out it was the vaccuum advance on the distributor. There is a diaphragm in this, I did a post mortem, which had perished. New unit fitted and problem cured.
This may be your problem.

With the engine running remove the vaccuum pipe from the carb and plug the pipe, on the carb. Suck on the pipe to the advance unit. There should be a noticable change in the revs. If not that is your problem.

Do a compression check for peace of mind. Its only 10 mins to do. Xflow stuff is all getting very old now, so perhaps look at a lumenition style kit to get rid of the points and a decent new carb, as if its original it could be 30 years old and tired !!

OK did most of what you all recommended, so a sort through, it turned out to be the Ignition Coil. a quick £20 fix. She runs lovely now very smooth and not missing a skip. Only taken it up and around a few hills and streets at the moment taking it out for a proper run with a support vehicle tomorrow. But all looks good thanks for all your advice i have no doubt by cleaning up and checking everything else contributed to the fix and smooth running as well.
