Don't block off the hole in the bottom of the carb with a gasket between the spacer and the carb. If you put a gasket there make sure it has a hole in it that lines up with the one in the bottom of the carb. that port supplies manifold vacuum to the power piston, without the vacuum there it will run rich and toast your fuel mileage
