1100 Clubman

[Heinrich]

Hi guys i am in need of advise. 
My Clubman was running great then left her standing for 2 weeks. I could not get the car to start again.I eventually took the car to a local shop and they got it going.(was told they fitted new plugs) I drove it for 2 weeks with no problem but could smell the car was running a little rich. ( petrol smell) A week later the car would not start. Got upset and decided to leave the car for the week end.This morning I bought the correct plugs as I always use the BP6ES plugs ,fitted a new coil turned the key. Car started straight up.  Drove to the local shop and when I got back to the car it would not start?  I am at the end of my wits. As mentioned it's got a new coil new plugs and a new electronic dizzy. I know it's not a trimming isseu as the car was running well. Can't be a points isseu as I fitted the electronic ignition. There is feul and spark? Could the carb be to rich causing the plugs the fail?  Please help.
I am in rustenburg so it's a drive to get to one of the mini specialists.
Any advise would be appreciated.
