My friend does many electronic ignition replacements and he did adjust the timing and drove the car a number of miles after the replacement was done ( although I don't think he buried the speedo?). The issue that may have created the problem was that the distributor wasn't tightened and we thought there might have been some damage to the trigger points as the car ran fine immediately? When I went to pick up the car, the car started but it wouldn't rev and wouldn't idle but when my mechanic did rev the engine, the voltage to the increased and opened up the trigger points?( Previously there wasn't enough voltage to the trigger points to open them up(?) ( supposition?). The initial thought was that the trigger points may have been damaged although they were previously checked by a MB mechanic and he did something to them and he told me I shouldn't have any more issues with them?
