May have accidentally solved my Judder problem

[Tall_Blk]

ever since TIT3 which i had to cut short, my engine tends to judder sometimes and cut out occasionally. sometimes it start immediately, on the rare occasion it refuses to start for about 10mins. Anyway, went out today, numerous visits. got in the car to start it to head home, car refuses to start. for over an hour i kept trying. i decided to check the connection of all the leads and i notice a very loose connection to the distributor cap to the ignition coil. pushed it back in and presto, the car starts straight away. it even appear to run smoothy or am i imagining this. anyway, i love these plain old easy to find your way round engines
