I too had an issue with MSD acouple of years ago. A part inside the distributor just fell a part. I called MSD as it was still under warranty, and got nothing but a run around. They wanted the defective part to send to their engineering dept, and if they found it defective they would replace, plus shipping; time about 2 weeks from they received the part. The replacement part was about $7.00 as I recall from Summit with delivery in several days, and I got a FREE cap. I later switched over to an ACCEL and no problems since. MSD's customer service leaves alot to be desired as far as I'm concerned.
