I'll let you know how I get on. Changed the plugs over to the old ones I had in the car and the car drives fine now. Jano at oddkid said the brass screw with spring on is for idle so I adjusted that and it idles ok now aswell . Im thinking either the gaps are out on the plugs or I didnt put one of the ht leads in properly . Next job is to check the lights and while checking the wiring solder any wires that have been bodged (Theres a few).
