"…Honestly I can't tell a difference - now my engine is stock, but still...cold starts, idling... The ONLY difference was that when my carb's idle circuit was going WAY lean and fouling the #6 plug the MSD would keep firing through all the crap, but otherwise with a proper carb it's fine…."
"… with a proper carb."
which carb? That's swapped out now? to what?
No longer "going way lean"?
The MSD is just so expensive for me…
