I bought a brand new MSD billet Disto...

I jjust built a new 383 with LE2 Heads and LE smog cam Big moith ported manifold, 58mm BBK TB, LT's, CSR EWP.. all the good stuff.. Than I decided to buy a new MSD Billet, bought it from ebay, got a good price... Some where along the lines, I lodt the instructions.. I assumed it was like other opti's aligh dowel and go... Well motor is in, all buttoned up and tried to turn it over and nothing.. I have fuel pressure, and all the wires are good, I even have a MSD coil..I checked and doubled check everything.. I could smell gas, so I knew I was getting fuel.. but no bang... I would EVERY once in a while get a back fire, type hiccup, but no fire... I took one of the spark plugs out and put a plug in it to see If I was getting a spark and nothing... I than did a search and someone said you need to disassymble the MSD and set the cap??? Is this true?? I dont mind taking it apart, but does anyone have any experiance??

Thanks

You should have disassembled the MSD when you got it, and loc-tited the rotor screws. - MANDATORY. Isn't unusual for the rotor to come loose. That's why the MSD, in many people's eyes, is not worth the money. OEM Delphi unit is adequate.

There's also the possibility you did not align the dowel pin correctly, but that would produce spark - just at the completely wrong time.
