Of course , stuff doesnt magically happen .
So here is the procedure.
First off , used the gasket as a template to drill the pulse line hole in the adapter. Cool . Then notice i did it on the wrong side . Fill up the hole , sand it down so it can seal , repeat drilling on other side. Then notice the pulse hole is on the wrong side , and because of the bolt holding the adapter to the engine , it cant seal. So i cut a groove connecting to the pulse hole on the carb , and its mostly finished. The gasket covers almost all but a small part , which will need more attention , but im satisfied with the progress.
