Rh to remove this pipe in the hot season—but it is an absolutely necessary feature during cold weather.

It automatically controls the flow of the gasoline into the carburetor. If it floats too low, starting will be difficult; if too high, the carburetor will flood and leak. A cork float which has become fuel soaked should be removed and replaced by a new one or thoroughly dried and then given a couple of coats of liquid shellac to make it waterproof.

No. The carburetor does not ordinarily require priming when the motor is warm, and starting with the rod pulled out is apt to "flood" the engine with an over-rich mixture of gas, which does not readily explode. This naturally causes difficulty in starting. If you should accidentally flood the engine, turn the carburetor adjusting needle down (to the right) until it seats; then turn the engine over a few times in order to exhaust the rich gas. As soon as the motor starts, turn back the needle (to the left) and readjust the carburetor.
