I thought I would post this here as it feels slightly like progress..........
Well, after a frustrating day in the garage I think I've finally discovered that my fuel gauge is possibly lying to me and over-reading.
To cut a long story short, there was more than enough fuel indicated on the gauge but none in the filter when turning over. I set the ignition timing back to basic setting as per Phils post on my non-starting thread and I then thought in for a penny and refitted the accuspark kit.
I got her running roughly and found she would happily suck fuel from a can at the front so I warmed her until the fan kicked in, took off the vacuum pipe and set the timing with a strobe so that the cutout on the wheel is pretty much smack bang inline with the centre of the W notch which I believe is correct?
I then figured maybe the lines were blocked or something, so I disconnected at the tank and fed it from the can at the back of the car and she still ran great, this caused me to have a slightly embarrassing and depressing light-bulb moment
I put the rest of the can in the tank, reconnected the lines and guess what.........
She now seems to be running pretty well, I need to put more fuel in but now I have a problem getting her to start. She takes ages turning on the key, with fuel in the filter then she reluctantly fires up and runs ok except there was a bit of a judder at one point.
Could it be that the timing is still not quite right or a new hot starting fault? I will try her again in the morning. As always suggestions gratefully received.
