Possible MSD Problems???

[AMiller]

Fired my 351W for the first time in the car after a several year storage nap. Before the motor was put to extended sleep it was built, fired, and broken in on the dyno. Everything was good then. Now its in the car and things are not as good as I hoped. Just cant get things running right.

The short story is the only thing that has changed from when it was dynoed to now besides where it is sitting is the Ignition box. I dont know what it was hooked to on the dyno.

I bought a MSD 6AL and Blaster 2 coil for the installation. Carb and distributor are the same.

Anyway, I can not achieve a constant idle or proper easy start up. Sometimes it pops and sputters along with being really hard to turn over. Other times it runs like a top but if you check timing it is all over. It jumps around over 30 degrees but sits there and purrs like a kitten.

Motors good, distributor is set correct after hours of screwing around, and carb was just rebuilt do to long storage period. Things should be working.

Thanks Guys,
Aaron
