Those little acrylic float level sight glasses you put on the side of your carb bowls, can
break off, if they are cheap, or been in a while, or if tightened down to much on intitial
install. Which means you could have a fire. Also, when unscrewing one tonight, I had to use a wrench,
due to it being in there a long time, and little shreds of plastic were left inside the bowl.
So I recommend once you get your float levels correct, use the brass plugs with o-rings instead.
