Surging 392

Okay, metering block was still not flowing properly. Needs to be rebuilt. Couldn’t find parts readily available, but Summit Racing in Arlington had a new block in stock for $43.00. Installed the block and carb. Fired right up with 5 inches more vacuum than I ever had before. Still not as steady as I like, but 16 to 17 in Hg is great. Also, I can know get timing below 5* without dying. Set timing to 8* and drove like a new engine should. Still need some tuning, but very happy with results.

I will post additional results and pics later to hopefully make this useful for others.

Right now I’m taken by a couple of days of with family. Happy Thanksgiving everyone!
 
Hey, that's excellent progress! Use your vacuum gauge along with your ears to adjust your air idle mixture screws for an optimum ratio. And be sure the screws are the same number of turns out from seated on both sides. Happy Thanksgiving!
 
Glad to here it's fixed. There are just passages in a metering block, so they may have plugged with the same debris as the jets. Enjoy the family and your running Scout. Happy Thanksgiving.
