Kick *** MRL 440

I've used several of the Summit Street Strip distributors, they are made by Mallory. I was briefly distraught by the movement that I found in the plastic arm that retains the internal plate also. The arm was stiff enough but there was movement around the pin, a quick dab of silicone removed any movement. I found that the infinite adjustability of the mechanical advance in the Mallory to be preferable to the bushings on the pins in the MSD. With the MSD I have to weld up the advance hole to limit the advance as I do in the Mopar distributors. I'm not going to spend $280-$380 on a MSD distributor that I have to weld on to get my advance curve correct. I now buy the Firecore50 distributors, they are rock steady and infinitely variable.
