In a previous thread I had theorized about a mechanical-stop to limit the advance on Loadomatic distributors. Turns out, someone on ePay is selling a vintage (?) Offenhauser part designer for that purpose. It screws into the diaphragm and limits travel with an adjustable stop. If your dampner/pulley were fully degreed, this might allow accurate re-curving without a SUN machine? A little trial & error twiddling of the spring posts to accelerate the curve, and you could theoretically limit the max advance with a timing light while the engine is running?



Which makes me wonder why there is always so much room for improvement from factory settings. I assume economy/smoothness/longevity?
