Sonnym, what jet did you unblock, the one under the bowl nut, or the plastic one on the top?

I'll try 2 gaskets. Yes the primer bulb has a hole in it. The new one looks to be the same as the old one apart from.being red instead of black.

It primed fine last year, but when I got it out this year it just won't prime.

The two gasket trick usually works and certainly worth a try.  As long as the bowl seal is good and the filter backplate is sealed against the carb correctly there should be no reason for none priming.  You're simply putting a little pressure in the bowl which pushes a small amount of fuel up into the intake. With the air filter removed you should be able to see the fuel entering the intake when you prime it. 

Let me know how it goes.

Kev, if that's the same engine in the picture from the link you provided then you should tip mower on to it's right hand side, towards oil filler. (just make sure it's cooled down a bit in case of fuel spillage from carb).

You would do the same when changing (draining the oil).

The crankcase breather is on the same (left) side as the carb hence why it dumped the oil into the air filter casing.

Their info is wrong if they say left.

Edit:  Just to clear up that "Golden Rule" thing, you often see this mentioned but in reality it's just there for people who don't understand how how things work, sort of a generic instruction.  You'll often see people telling others to only tip the machine backwards resting on the handles as well.  Although this is probably the safest way to avoid these issues it's also the most awkward way because the machine is sitting at a angle meaning you virtually have to climb under it.

Hi Kev, and welcome to TGMF.

I'm not sure what engine is fitted to the Parker brand machine, but if you have a photo of it I can probably advise on the best way to tip it.

Regarding running now, you should be ok as long as the engine pulls over ok.  Just make sure the oil is up to the correct level. You might need to remove the spark plug give it a clean and pull the engine over a few times to clear any oil in the cylinder.  It might smoke a bit when it first starts.

Yes that's the one.

Have you tried fitting two gaskets between the air filter backplate and the carb.  The plastic backplates have a habit of distorting and that in turn causes priming issues.  I quite often fit two gaskets.

Also make sure you fitted a primer button with a hole in the middle of it, It needs that hole.

Sonnym, I moved your original post to the correct board, and replied.  You can find it here, https://thegardenmachineryforum.co.uk/index.php?topic=865.0

Hi Sonnym, and welcome to TGMF.

There is various videos on the web showing how to do this, and it's probably easier than trying to explain in text. 

This video below explains how to do it, though you might not have access to a Sonic leaning tank, you should be able to clean it sufficiently without.  It will give you an idea where the jets are and how to access them.  It's basically the same type of carb you have.

Thanks.  So the primer button is at the front of the engine and fitted into the plastic air filter backplate?

Hi Somerset, and welcome to TGMF.

What engine do you have on yours. Briggs and Stratton? or Tecumseh?

A little sketch I made of the basic variable speed system the manufacturers are using nowadays.  It's not to scale or anything, but just outlines the basic principle, and how it works.

I'm not sure there is a workshop manual for this machine, they are not as common as they used to be, and probably if there is any service data info would only be available to their service dealers.

Would it be possible for you to send me a pdf of the manual.
I have just bought a 725 and have a few problems with the steering.
If not do you have a link to a source?
Thanks
Robin
