running poor?

[Jiffer]

I gave my mk2 cortina a damm good run yesterday and it ran realy nice.

when I started it today its running ruff? It has a newly built 16xflow with 40s and leccy ignition on it, which were all set up for the engine on a RR.

what do I look at 1st?

cheers

Dampness, Was it raining when you took it out, screw fallen out of carbs, also check plugs for fouling, difficult to guess really, when you say running rough, do you missfiring or just running lumpy

[Jiffer]

wouldnt say missin, just lumpy, yes it was raining, dont know if to check tappits etc as its been a new build engine.

Might be worth a try

my lil 1300 had dropped a 2nd valve now, and headgasket has gone, just waiting for it to blow any day, should have me 1700 in there in 3 weeks

[Jiffer]

dont know if this was the cause but the pipe from the manifold to the servo had a big split in it

That wouldn't have helped it, air would have beeing sucked into the manifold
