I haven't worked on many combe lifts but I might be able to help you first are you not getting spark to coil l would check the pick up coil inside the distributor there will be two wires ohm them out they should ohm between 500 and 900 ohms also give a light pull on them if they break that is your problem also undo them to ohm from module. If you need to change the distributor must be removed to install. hope l was of help.
