kiwi-jim Posted March 16, 2019 Report Share Posted March 16, 2019 Hi everyone, can anyone tell me are the weights at the base of the 25 d4 the same across the models. i need to build up a distributor for my TR4 the current reproduction options are way to erratic as the internal weights and springs are hopeless. I have two old Lucas 25d4 off other cars based on the model numbers one with a 17 deg cam one with rebuilt cam now stamped as 12 degree. What I want to know regards the weights and the springs. Are the weights normally the same size, weight across models? I know the mechanical advance cam varies across different cars , it’s the weights I am wondering about currently. Thoughts ??
