Prevents explosions on inboard gasoline engines
A carburetor backfire flame arrester is designed to prevent flames or sparks from escaping the carburetor during a backfire. It is typically located at the top of the carburetor and consists of a mesh screen or metal plate with small holes that allow air to pass through while trapping any flames or sparks. This helps to prevent potential fires or explosions.
That is to allow even heat distribution. If the object being heated in a flame is held in one position, a "hot spot" will occur and the liquid may start to boil at that spot.
The color in the flame test has to do with the electrons moving from their ground state to their excited state. When the electron tries to move BACK down to the ground state (near the nucleus) it emits energy called a photon, this is how you see the light.
The pilot flame is/should be about 1.5" long, the diameter of a pencil. When the burners are going, the gas is shot into the burner manifold, and the gas sent to the burner is designed to go to the back of the heat exchanger. So, in a typical 80,000 input heater, about 14"-18" long.
The heat energy in the flame moves the metal atoms in the chemicals to a higher energy. When they reach the ground state which is there original position they give back their absorbed energy in the form of visible light.
when alkali metals are exposed to flame test, the loosely bounde electrons which present in valency shell are excited to higher energy levels, after some time they will come back to ground state by emiiting radiation which falls under visible region gives colour.

Not shure
back up
Could be in need of a tune up and/or a carburetor rebuild (accelerator pump failure).
The carburetor needs rebuilding.
because on the none safety flame you get bigger burns, on the safety flame it isn't as strong
no
There are several reasons there can be a leak. However, you will want to take the carburetor apart for any leak - purchase the carburetor kit and carefully take it apart. Use the rebuild kit to replace gaskets, etc. and when you put it back together, the leak will also be fixed. Do not use gasket sealer on the carburetor.
there is 2 clamps. one on the front and one on the back
its not the carburetor that pumps fuel, its called a fuel pump, that's the problem
To prevent a back-fire which results when unburned exhaust collects in the engine area
The float could be stuck open in the carburetor, causing the leak. The carburetor leak needs to be fixed, this could be all of the problems, it also causes a fire hazard.
