I cant say it doesn't have a vacuum leak but I highly doubt it, I have a good vacuum at the manifold, more than 40" water gauge cranking it over. That is between the engine and carb, on the manifold.
I put all new hoses on it as well and have leak checked them. no leaks.

I have tried spraying ether around all the gasket surfaces on the intake to see if it would get any into the engine, it didn't.
