HELP...Broken Manifold Stud!

You did suck it up through a vacuum line right, then let it sit or just power through it? My Breeze has an updraft intake and originally, the seafoam didnt get into the cylinders, just pooled in the log. I used it again through the power brake line at a fast idle and it billowed smoke for 2 minutes like a skywriter. If you get it to run great, dribble water (like a garden hose just barely on) into the carb at a fast idle and itll steam clean the cylinders like magic.

It was a 16 oz. bottle of Sea Foam - 1st used 1/4 in the carburetor (slowly) at high idle, then 1/2 in the Oil/Valve Cover, then 1/4 in the gas tank. Very minimal smoke.
