Hi,
I'm having a problem with starting my 1256 viva. It seems to catch but doesn't run, no matter what I do with the timing and carb tuning. This problem has been getting worse with time as it started with the engine running rough and spluttering when I rev the engine.
This started happening ever since I changed the power brake vacuum hose, which had a big split in it before.
The car seemed to be running fine before this happened. I have disconnected the vacuum advance and it still won't start.
The last time the car was ran, it refused to start as it had a bad battery earth cable. I removed the starter (and alternator) in diagnosing what was wrong before finding out it was the earth. I since changed the earth cable and the one time I started it seemed to work fine (I think).
I have since replaced the ignition coil which didn't change anything, and the car is fitted with electronic ignition.
Does anyone know what is going wrong here? Is it a bad spark? I have really been struggling with this problem for a while now and any help would be greatly appreciated.
