mallory unilite, im thinking of getting one Options

[mrbubblehead]

i just got my carbs dialed in perfectly. and im thinking about getting a new ignition system. i want to get rid of the 009, and replace it with a vacuum advance unilite with the promaster coil.((im going after MPG) but after researching the unilite, it seems the newer models are prone to problems compared to the older units. is this still the case? any mallory users out there? particularly the newer models?

If you get a unilite, make sure you buy the circuit guard box they sell or you will
fry your ignition module ($90). Ask me how I know. Also, make sure you have
a ballast resistor wired properly if you are not using a ballasted coil or you will
fry your ignition module ($90) as well.

I am using a unilite with my Raby 2270. I have not used any other distributor
with this engine so it is hard to compare. I can tell you that my idle is never
100% stable on my digital timing light. I tends to bounce around a 40 rpm
range all the time. I think there is some play in the shaft and internals that
causes this. I replaced the pin in the shaft that came with the unit with one
from an old 090 which was better but still not perfect.
