Finally bought the Mr. Gasket
Using my low-tech tension gauge, I was able to do some comparisons.
DS II Smaller Spring (Blue) 1/8†pull = 4 oz./ ¼ lb.
DS II Heavy Spring 1/8†pull = 6 lbs.
Industrial 2300 dizzy, Light Spring, 6 coils 1/8†= 2 lbs.
Industrial 2300 dizzy, Heavy Spring, 7 Coils 1/8†= 4 lbs
925D Spring (Both look the same), 1/8" pull = 6 oz.
Without a Tach, Distributor Machine and a dial-back timing light, I won't really be able to test the impact of replacing the Heavy Spring. It looks to me, so far, that the 925D Spring is actually a little heavier than the light spring in my DS II, so it is actually going to delay the centrifuagal advance.
I'm tempted to use the 4 lb. spring form the old 2300 dizzy, as it's 2 lbs. lighter. The 925D is likely too light to replace the heavy spring, as another member found out.
Hypothesis: For our puposes, save your money ($3.99 + Tax), don't bother with the 925D springs.
