Thanks BenK for the details. I saw the flyweight trigger mechanism in the videos, but I didn't realize from the videos that there was a clutch also in the mechanism group.
Many thanks for the info. I'll report back when I take the K2500 Burb back to my friend at the local Chevy dealership. This time I'll get details on what is in the Astro G80 and what goes in the 2500 Burb G80.
For Synthetic, I see that Mobil-1 offers a 75-90 and a 75-140. BenK, do you use the 75-90?
