Ongoing running problems

[andy8688]

Thanks to everyone replying to previous topics.
The problem I have with my car is after a few miles it develops a judder like running out of fuel, then engine backfires, Im talking pedestrians taking cover, then engine stops.
If I leave the car for about one hour it starts fine it will go for about 3 miles, I have checked everything people have suggested, the latest one was the earth wire connected in the distributor, it turned out not to be that. I have had it tuned middle carb piston is a little sticky but assured would be OK.

Any more suggestions, my engine and carbs were all rufurbed 3 years ago.

Andy,

run it with the fuel filler cap off - they are vented and if blocked can cause problems (not the misfire though!). Worth a go. Try replacing the condensor.

Have you replaced the condensor in the distributor? Is the coil new? is the fuel pump delivering fuel when the engine stops?

It might be worth giving a summary of what you have done so far.

[andy8688]

I have checked all filters, replaced plugs, leads, dizzy cap, points, condensor, coil and checked timing, I have had the carbs tuned and balanced, apart from the middle piston sticking slightly.
I was talking to someone today who owns a series 1, and he had a similar problem it turned out to be a faulty coil, so I have ordered another, will let you know how I get on.

I had something like that many years ago on a Ford Capri - it turnd out to be the condensor. Also had something like that on a much older car even earlier in my motoring youth and changing the coil and condensor cured it

It also sounds typical of rotor arm failure, where when hot the arm shorts out, and once it has all cooled down, the earthing pathway closes off . This is a result of poor material in pattern as opposed to genuine Lucas rotos

Thank you to all your all of your replys, the problem turned out to be a very old and tired wire which connects to the negative of the coil, and down to the connector on the plastic bit which fits between the dizzy and the cap part number RTC175.

What a transformation, so simple, but taken a long time to solve.
