Primer bulbs on small engines take the place of a choke on the carb . If your carb has a choke on it then you could probably bypass it . The object of the primer and the choke is to give the engine a extra charge of gas to help it start when the engine is cold . If you take this away then the engine will be hard starting if it starts at all .
The choke enriches the mixture for start-up and then is heated by a small electrical heating coil so the choke goes off when the engine is at operating temperature.
You can get an automatic choke for small engines at most hardware stores that sell mower parts. You can also find this item at many small engine repair shops or even golf cart shops.
To activate the automatic choke on a small engine, such as those found in lawn mowers or chainsaws, simply start the engine. The choke is usually controlled by a mechanism that senses the engine's temperature or throttle position. As the engine warms up or the throttle is applied, the choke will automatically adjust to allow more air into the mixture, thereby reducing the choke's restriction. Always refer to the specific equipment's manual for precise instructions, as designs may vary.
A 454 Chevrolet engine which is experiencing a choke light while the choke is physically open, indicates the choke is not receiving power. This can be caused by a loose connection or a defective choke.
It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
