Does my Craftsman push mower need to be empty of gas before i replace the bad primer bulb?


no it doesn't. the primer bulb is on the air filter. it will just pop off with a pair of pliers and push the new one in with a socket. fairly easy job. good luck

I replaced the primer bulb and I can't get the gas


A common mistake while replacing primer bulbs is getting the lines reversed. Try switching the lines, then push the primer bulb and see if it draws in fuel.

I Have a push lawm mower (mtd product model # 11a-439s729) serial# 1d261k81143 I have to prime before pulling the lanyard to start . I have no problem starting the engine ,the real problem is it will die...


I really need your engine number but I am going to guess that it is a 3.5 to 4 HP Briggs & Stratton with a black primer bulb on the side of the carb.

Try this the next start. Take a screw driver handle just a bit smaller than the primer bulb and FORCE it against the carb body trying to make a seal with the primer rubber against the carb body. You use your thumb if you can manage to depress the entire area of the center of the primer bulb agains the carb body. If it runs normally when you do this..... the Primer Bulb has a pin hole in it. (No joy..... read on)

If after doing the above you strill have the same problem remove the air cleaner and tighten all of the screws that mount the carb to the gas tank. Often over time the carb body will warp and then it starts getting air introduced into the diaphram that is between the cab and the gas tank. Tighten the screws. There are usually 5 of them. (Remember the body is plastic.... tight but don't break it) Then try another start.

If that does not work the diaphram between the carb and gas tank is probably damaged and will need replaced.

If you need parts info respond with your engine number or go to www.briggsandstratton.com and look it up for yourself using your ENGINE TYPE MODEL SERIES number found on the air shroud above the spark plug.

Thanks for choosing FixYa.

I have a Craftsman Gold 6.0 mulching mower with a B&S engine on it that has been idle for about 10 years. It was only lightly used before that and I ran the gas tank dry before putting it away. Today...


Sounds like the primer bulb dry rotted from sitting &/or the float is stuck in carb. If gas is indeed leaking from bulb. It will need to be replaced. While it is apart, clean carb inside & out with spray carb cleaner.

The tank vent is a bronze plug inserted into the tank casting--the caps are not intended to vent. Check the fuel filter for plugging and the condition of the fuel lines and primer bulb. You should be able to fill the bulb with fuel after several pushes of the primer bulb. Have the fuel lines been changed? Hope this helps!

Will not start. Primer bulb does stays pushed in.


that happens frequently on older equipment ... the alcohol in modern gas can damage the fuel lines and primer bulbs if used in tools not designed for it .. even replacing the damaged parts doesnt help .. since the replacement parts are often made of the same stuff as the original .. you have to make sure the parts can handle alcohol ... i dont take anyones word for it .. i soak them for a few days .. if they swell up or turn white .. then those are not compatable .. if you cant find alcohol resistant parts then you can still get gas that doesnt have any if you ask around .. ... if your tool is a more recent vintage then it should already be compatable .. maybe you have a clogged passageway in the carb or the primer bulb my just be aged .. if you cant get the primer bulb to work then you can try spraying a little starting fluid on the air intake (air filter) .. that should get you started to see if anything else is wrong .. if the primer bulb is damaged then chances are the plastic fuel line is also .. primer bulbs and other parts are usually available from the manufacturer and from parts supply stores ..
