They have um for other machines on eBay...some may fit your machine and may carry some at your local small engine/lawn mower repair shop. Compare your type to the ones you find.

SP740 mountfield mower is not doing anything when i push the primer button. i used to hear and feel liquid but its empty just hear air. i have oil and petrol in it, what am i doing wrong

there is a contraption in electronics called a diode. it is a one way street, current can only flow one way. well in the socket behind the primer bulb is a flap which does the same thing with fluids. either the flap or the bulb as become corrupted, or the small passage the fuel is drawn through has become plugged. you need to get a rebuild kit, take the carb apart, thoroughly clean it, and then put it back together with the parts from the rebuild kit

How do I change the primer bulb in my homelite vac attack 2

Most primer bulbs have small metal ring holding them in place. If you are careful you can usually pry this ring out in one piece but when you purchase a new primer bulb they usually come with new ring and you don't have to be so careful getting it off. Good Luck...

My briggs and stratton 158cc 500series push mower primer button melted from sun. how do i replace it?

There is a tab on either side of the carburetor right where the primer bulb sits. You can depress both of these tabs with a screwdriver and pry out the plastic ring that holds the primer bulb in place. You can purchase a new primer bulb (with a new plastic tab) from a local mower shop or from a small engine repair shop. When you install the new primer bulb, put the rubber bulb in first then put the plastic ring on top and press it in until the tabs click on each side. It should work correctly after the tabs are clicked properly. You can take off the air filter and look into the carburetor to see if the unit is priming correctly. I hope this helps you out.

How do I replace primer bulb on mountfield SP470 lawnmower

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

How do you remove the primer bulb on a model 10a902 Briggs and Stratton mower engine?

Look at the outside of the plastic housing where the primer bulb is inserted, you will see an open area where there are 2 tabs, one on each side, using a small screwdriver, push these tabs inward to release them and slide the whole thing out of the hole including the primer bulb. The new primer bulb normally comes with a new mounting ring if you purchase it from a lawnmower dealer

What fuel do use in the mountfield HP470 petrol lawnmower is it a 2stroke mix?

No. This is a 4 stroke engine and it uses regular gasoline, not a mix.
