Bad spark?
Hi Peter,
i´m sure with this msd ignition you have to delete the ballast resistor - did you? Maybe that´s the cause for weak spark - low voltage due to the resistor.
Make sure everythings grounded good. Don´t know the wiring details, the manual should tell clearly.
Regarding TDC: same with my damper, i made a new tdc mark and use a timing tape. I personally always check tdc at cylinder 1, with heads on you can use a straw or something, put it into the spark plug hole.
