Bad idle after starting, need help.
Ok well heres whats been happening for the past month or so in my XF. The engines a recon, 4.1 carby, and its done less than 25,000 K's roughly.
It seems to take 2 tries to start the thing lately. Like if it starts the first time, it just dies as if theres no fuel getting to it. Once it starts the second time, it idles real rough unless I give it a few big revs. This seems to be the only thing to stop if from idling rough and shaking like nuts.
Now it only does this when its been left overnight.. and if i start the car up a second time in the same day, it will be normal and it wont happen.
Also once I start it in the morning, and take off down my street some black smoke comes outa the exhaust (for like 5 seconds). But if I drive off fairly fast then less smoke will come out (maybe only 2 seconds), and then it wont do it again untill the next morning. If i dont take off fast, then the car will continue driving roughly with smoke coming out (usually around first gear only) untill i floor it a bit and then its fine after that.
It seems as if theres maybe something in the fuel system every morning, and its blocking something, and unless it gets a few big revs it wont clear up... i dunno??
Any suggestions people? its really starting to shit me off :(
EDIT: Also I just noticed, that most of the rocker cover bolts are hand tight.. hmm that aint normal... :( How tight should I put them on?
