Look in where the bulb goes into the shroud. There will be a snap ring in there. just remove the snap ring and the bulb will come out. Make sure you replace the snap ring and check the hose to the carb.

Your engine model # 128602 Type 0212-E1. Forget about ordering from Sears and paying shipping and waiting a week. Go to your local Briggs and Stratton dealer (most shops are) and buy part # 694395. Should cost about $3.00

SOURCE: How do I replace primer bulb on mountfield SP470

I believe this mower has a Briggs & Stratton engine, if that is the case:

Look at the base of the primer bulb where it is mounted on the carburetor, you will see an opening on both sides of the plastic that the bulb is mounted in where the locking tabs are.

Take two small screwdrivers, press in on the tabs and pry toward the outside of the housing at the same time to release the tabs and bulb. Pull the entire bulb and mounting ring out as an assembly. Don't worry too much about damaging the ring, a new one should come with the new bulb, in fact, it would be wise to purchase the new bulb prior to beginning so you can see what you are working on

Carburator issue. If you have some mechanical abilty you can pull the carb off else take it to a shop. You probably left gas in it off season. Either the main jet is clogged or the float valve is stuck. Either way, remove the carb, tae off the bottom cover and clean everything out with gum out or a carb cleaner. reassemble and eveything should be fine.

Why my weedeater idle to high and why air bubble in the primer bulb?

Its not un common to have air in the primer bulb, Check for a possible air leak in the system. This will make the saw idle higher than normal if its sucking air from elsewhere.

My Craftsman 17cc gas weed trimmer wouldn't start.

Hi There, Check the primer bulb for tare or pin holes. Replace it. Check and clean carb jet it maybe plugged with debree. Also check for spark which you didn't say. Replace with correct plug.
Note; Do not use strong cleaners on rubber seals (O rings and gaskets) They dry up and crack.
If needed use a dabble of grease on seals

Try swapping the hoses at the primer bulb. You may have put the return hose on the purge side of the primer bulb.

I am replacing a primer bulb in a chainsaw and the lines are gone so i need to find out which line goes where

Leave both primer ports open, then attach the fuel line that feeds the carburetor from the fuel filter to one of the primer ports--pump the primer and if you guessed correctly, it should pump fuel into the primer bulb. That is the primer port that goes to the carburetor output connection. The other primer port connects to a short line that goes back into the fuel tank with no filter. Return the original feed line back to the upper carburetor port. Connect the open primer port to a short line that connects to the carburetor lower port. Be sure to use original rubber lines, not plastic. Hope this helps!

Poulan P3400 Chainsaw Fuel Line Routing

If the saw has a primer bulb, then you require one line from it's output out to the tank return. Another line runs from the carburetor outlet to the primer inlet. Make sure that you use original rubber lines, not plastic replacements. The primer ports are found by trial and error--hook the filtered line directly to one primer port and leave the other port open. If the bulb is in good condition, and correctly connected to fuel, the bulb should fill with fuel after several pumps. If nothing, reverse the port connection at the primer--and pump test again. One of these two connections should allow pumping to occur. When you get pumping, install the tank return line to the empty primer port. Remove the filtered line from the primer and install on the carburetor. A new piece of line runs from the now empty primer port and connects to the output port on the carburetor. If the carburetor lines are correct, you should be able to pump fuel through the carburetor body and out to the primer bulb. If nothing happens, you may need to swap the carburetor lines, and you will likely need to service the carburetor. Hope this helps!

How to instal primer plunger on Toro Snow blower 1000E

The new primer bulb should have come with a plastic retaining ring. If you have the new ring then pull the old ring and primer bulb out with long nose pliers.
Then you insert the new rubber bulb until the outer part of the bulb face mates with the carb face. Then install the ring press both pieces into place until it is just below flush.

(If the new bulb did not come with a new plastic ring... you are going to have to ever so gently coax the old ring out with your fingers crossed hoping it does not break.) I have personally broken more than 50% of the old rings... trying to get them out.

Thanks for using FixYa.

Need diagram/instructions on how to replace primer bulb on briggs and stratton push lawn mower My primer bulb has busted so I'm trying to replace. Don't know how to get the old one out and replace.

Unless they have changed, all you have to do is unscrew the old primer bulb and screw the new one on in it's place. The primer is composed of the rubber bulb with a metal or plastic ring with threads on it where it connects in the fuel system.
