Title: Plugging large hole on the front of top.
Post by: 77cruiser on December 04, 2015, 03:18:17 PM: What do you guys use to plug the emission hole 3/8 tube on the front of late model carbs? I think it's the charcoal canister hose.
The hole is .371 thought 3/8 cup plug would work but they measure .385.
I made a nice brass plug tapered it on the lathe, but something easier would be nice.

How about filling with lead?
