Why does a Briggs and Stratton 4.5 HP lawn mower engine stop 2 3 seconds after it starts unless you continue to prime it?
it is losing its prime... i have the same problem right now and i have cleaned the carburetor, changed the gas and spark plug and changed the air filter. The only thing that i can think of is that there is something wrong with the priming bulb or the gas cap is hindering the air flow... still trying to repair....
What if your Briggs and stratton 6.5 HP will not prime?
If what you mean by not priming is the red primer button not priming, replace it. They are easy to find from a mower shop and hopefully doesn't costs alot. If what you mean is it doesn't primes itself after starting, replace the diaphragm pump located at the bottom of the carby and at the top of the fuel tank
How do you replace prime bulb on a Briggs stratton engine?
Very difficult without proper removal and installation tools provided by Briggs and Stratton. The old one can be removed with needle nosed pliers, by gripping as much of the bulb as possible and rocking it back and forth until it pops free. If the bulb tears out, be sure to remove the snap ring holding the base. Be more careful when installing the new one, as it can be torn easily. Put the new bulb in, and snap in the new retaining ring using two small flathead screwdrivers.

Your float is probably stuck or your fuel system is dirty. Try some carb cleaner if that does not work you may have to take the carb apart and clean it. good luck.
How do you start Briggs and stratton weedeater SQ 4.5?
Put fresh gas and stabilizer in it, and prime it with the red prime button. I just bought one from a guy who couldn't start it. Now that I know it will start, I will change the oil and maybe put a new spark plug in it.
Why won't my Briggs and Stratton 4.5 HP lawn mower engine prime I have removed and cleaned the carb. The primer worked properly before disassembly. Now the bulb won't shoot fuel into the carb?
The primer bulb probably needs to be replaced unless either one of the fuel hoses leading in and out of the primer bulb bracket is clogged. Be sure you mark how each fuel line goes before you remove the bulb so you can replace them correctly. Hmmm. Thinking more about it: If the primer worked properly before disassembly, chances are you crossed up the fuel lines when re-installing. Try switching them.
