Jeff,
Exactly the same problem, here. Drove a large socket into the hole to
expand the crushed glass, then added one layer of bid to the outside.
After that cured, I added three layers of bid to the inside. Problem
solved...
Don't close the air duct. You need all the air you can get, to those
carbs...
