Agree with rustyratrod. Definitely needs more converter, but also agree there could be other issues which guys have pointed to. I’d do the simple things first. I’d probably lock the distributor out instead of constantly fighting with weights and springs to get it where you want it. That eliminates any issue of when the timing is fully coming in. And if it still doesn’t respond to that, then you at least you know you have issues elsewhere. Just my thought.
