How to Replace Primer Bulb

Typically a primer is only used on 2 cycle engines not on lawnmower engines, so it would not have a primer bulb.

its probably a tecuseh engine no fix for that other than put new primer ball on

yes useing a thin small screwdriver slide it down the side and work the spring slowly out revers this to put a new one in

Do you have fresh gas? Make sure the choke on carb is working, maybe drain the gas out of carb and or clean it out, check for spark

This sounds like fuel starvation. This is usually caused by debris in the fuel float bowl or a dirty fuel filter (if used). Remove the fuel float bowl and clean out the debris. With the bowl removed use a spray paint can lid as a catch pan and check fuel flow. With the float down it should fill the spray paint can lid in about 10 seconds. If you do not have this much fuel flow you need to inspect the tank outlet port, fuel lines and filter (if used).
The 20029 & 20099 models came with either a Briggs & Stratton or Kohler Courage XT7 engine. I need to know what engine you have to provide any diagrams on what to check or clean. A n engine model number would be even better. (Please!) Since the post is labeled with the 20099 model I will cite that as a reference. This SERVICE manual should help you with repairs:

See page 27 of the manual for fuel filter location. (Optional if used) AN exploded view is on page 31.

If you have the primer bulb model see page 24 and note the ondition of the primer bulb and primer bulb hose. Any hole in the primer bulb or cracks in the primer bulb hose can also cause this symptom.

If you have the Briggs and Stratton engine (Model 20029) I need the engine number to get you the correct manual data please. Otherwise...this should help you resolve the problem.
Thanks for choosing FixYa,

Lowes Home Improvement store carries them, also lawnmower repair stores have parts departments that have them. Mine cost about seven dollars.

remove carburetter air filter cover,two 'torx' screws on top.primer bulb is retained in case by 2 plastic 'ears' push ear[s] in& bulb slides out of case.make note/label 2 fuel lines attached; one 'stem' on primer is longer than the other.replacements can be found @ lawnmower/small engine repair shops.

these carb /air filter housing gaskets were notorious for warping? there are 2 screws behind the air cleaner remove those and disconnect the throttle cable pull the black square housing off and replace the gasket with a rubber one from local mower shop?
