thanks for the reply so here goes
1.I believe it is running rich - is this a problem? If so how do I solve it?
2.The smoke is white and does dissapear after the car has warmed up.
3.Is the clearances in the head-gear being too far out of tolerance a problem and again if a problem how do you sort it?
4.Any idea on my hand brake?
Not a problem. I would say:
1. It's not a massive problem but it will make the car use too much fuel, under-perform and (only in very extreme circumstances) can lead to premature wear as the fuel literally "washes" the oil off internal components. You'll have to look into what the automatic choke is looking for to determine whether it is on or off - I suspect it's either stuck or sticking and / or receiving an incorrect sensor reading - I don't know enough about your model so I would buy the maintenance CD to be sure. Also, are your air filter and spark plugs new and clean?;
2. OK, sounds like it is running rich and is solved when the choke returns the air-fuel mixture to normal, so I think you're OK on this. It will probably be also burning off the moisture in the tail pipe in these colder months. So the main issue is to solve point (1);
3. Yes, over time this will be an issue. The only way to sort it is to have the clearances adjusted. However, on reading up on your model it sounds like the cam variator could also be a culprit(http://www.alfaworkshop.co.uk/alfa_145_146.shtml
) - was this done with the cambelt? The reference to bearings really builds on what I was referring to about oil on startup;
4. Yeah, it sounds like your new pads are not bedding in too well. I would take them off again, give the disks a really good clean with a de-greaser, make sure the pad faces are not glazed - if they are then they need a bit more time to bed in or rough them up with some sandpaper - be gentle and be sure you are happy you know what you are doing. Also check your handbrake cable is actually moving the actuators on the callipers - and that it is properly located all the way back to the handbrake itself
I think, though, that ten minutes at a garage will have the problem diagnosed and I don't think you have a massive problem on your hands.
