Even a broken clock is right 2 times a day.
You got pretty lucky that I happened to have the parts when you needed them...luck-ee-er yet that they worked at all.
Mess'n 'round with my quad-dual Power Ram today at work. I had a Mallory YC distributor (two piece cap) machined down to fit the manifold yesterday. That should look pretty "old timey". When I went to lock-out the advance, there seems to be another advance mechanism under the bottom advance plate with some additional advance with a single heavy spring. Kinda weird. Anybody here fiddle with the old Double Life 4 lobe cam Mallory sparkers?
