You can get tiny filters for the breather tube... (best not to leave it open, but it has to breath)...
Toss the vacuum hose and block off the vacuum tap on the carb. I used a screw in the hole,. The right size won't damage the tap and will be reversible if needed... Rubber plugs will rot away fast... (or just stick a golf tee in the hose as it comes off the tap. The goal is to stop that tap from sucking air and making a vacuum leak in the intake)...
