Hi Folks Sorry to have been silent on this for so long - other things got in the way. So -- I could not get my car to start, and I had tried everything I could think of. I sent it to my local Jag specialist. He managed to get the car started after adjusting the carburettors and rechecking all the ig...

Hi Folks Just letting you know that I have decided that this problem is beyond my capabilities. I will ask the Jaguar specialist guy I know to sort it out once he gets back to work. I am doing no more on it. I will let you know what the outcome is. Once again, thanks for all the help and the suggest...

Hi folks, Thanks again for further suggestions. My car does not have any of the later emission control additions. It does have the air pipe from the back of the exhaust manifold round to the intake on the AED unit. So far as I can tell, that pipe is clear. I tried putting a spare spark plug on each ...

Hi PPV I have the SU HIF7 carbs, which have the petrol/float chamber integral to the body of the carb. So its not possible to check the level of petrol with the carbs on the car. When I took the carbs off, and opened the bottom cover, both carbs had plenty of petrol in them, which duly spilled out i...

Good spark on every one, at a distance of about 5mm from the block. And each plug looks a healthy dry brown colour, so...

Hi Folks, thanks again for the suggestions. I tried a few more checks, but no real discoveries. However, I also decided to dismantle the in-line fuel filter which is found just before the fuel line feeds into the carbs. I had done that previously, checking that the filter gauze was ok (which it is)....

Hi PPV -- Thanks for the response. I have run the petrol into a plastic bottle, and that's the way I measured the flow rate. Its the same rate on both pumps - 1.2 litres per minute. I will try the trick with the spark plugs on Wednesday. I have seen that mentioned in the workshop manual, but since m...

Hello, this is my first post. I wonder if anyone can help. I have a 1977 XJ6 4.2 Coupe (Series 2). I only do about 300 miles a year in the car, generally taking it out for a 20 mile run once a month. Recently (last 3 weeks) I have had a problem whereby the engine starts first time every time, but on...
