I have a new Unilite that I got from the senior Tech at Mallory when they were here in Carson City. I never used it because I have so little vaccum with my cam. I've tried to sell it for half of the Summit cost with no takers. Can anyone tell me exactly what it is about Unilite that make it so unpopular? The only issue I have ever heard is that about 20 years ago they blew easily when replacing a point ignition distributor because of too much current going through the points. Today almost nobody uses a points ignition. Most have box of one kind or another( Mopar/MSD/Accel/Crane etc.). I am really confused. Do people really believ that a product will not be improved and issues fixed in 10-20 years. MSD had junk when they first started. My friend who builds high dollar engines has a a pile of bad MSD stuff from way back. He used to tell you that if you didn say Mighty Sorry Device, you either had to spit on the floor or leave his shop. Now MSD is the leader in ignitions. Why do people hang on to an old rep for Mallory Unilite?
