Once a LT-1 I had built was acting weird backfire some would'nt idle, long story short,
found rotor out of phase was almost half way between cylinders and optical sensor showed out of range,probably had slipped on shaft,I slotted the wheel and got the opti sensor in range and slotted rotor and phased it ran good then.
When rotor etc exploded could have knocked out of phase,I used a small degree wheel to turn engine to where ignition timing was so I could check phasing of rotor
