Just wondering if anyone has ever used the J685 limiter disc that limits the mech. advance in electronic dists. from 4seconds flat? If so how good is it? It appears to be better than welding up the slots. Although I do need more than 18 degrees mech. which is the max. limit it will go. Thanks, Dave.
