Early Sun Tach and MSD

[scuncio]

Hey everyone,

Wondering if the mid-'60s Sun tachometers (those which require a transmitter) work okay with an MSD 6AL? Any needle flutter, etc from the multiple sparks?

Thanks!

A friend has a '71 340 Duster with the sun tach that requires a transmitter box. He put in a MSD box and the tach went crazy. BTW, he's the original owner and the car still has cool speed parts on it from the early '70's.
I also read on another site where someone was running a Sun Super Tach that does not require a transmitter box and the MSD box would not run with that tach either.

MSD sells a Tach adapter for use with a 6a series box.I needed one with my Sun Super Tach II and my Stewart Warner 960..
