Screwfix Petrol Stimmer Advice

I have bought a Titan TTK587GDO strimmer,these are sold by ScrewFix.
It was £10 non runner.
Spark is fine.
Petrol / oil is new.
Spark plug is new.

So i tried to get it started but nothing.
I removed the air filter & give a squirt of carb cleaner down the carb,give it & pull & it started & run until the carb cleaner was gone.
It does this every time.

So i removed the carb & cleaned it with carb cleaner,no gasket / diaphragm look broken.
Put it back together but same issue.
If i pump the primer say 3 times i see fuel being squirted from the little hole in the bottom of the carb,this is the square plate held on by 4 screws & has a circular dish/raised part.

Carb off again & this time another good squirt of carb cleaner down every hole / pipe / drilling.
I just dont see why it wont even start if all is clean.

Any advice.

There’s no way that fuel should be escaping from that plate would indicate a split diaphragm in there to me.
John :)
If i put my finger over the diaphragm slightly and blow through the metal pipe i can see /feel it lifting etc.
Would this then indicate that there is no rip as otherwise the air going in would just come straight out of the rip ?
I like your theory but there still shouldn’t be fuel there is an issue somewhere.
Time to find out who makes the carb.....Walbro, zama or could well be a chinese make who’s name escapes me.

So you are then saying that the fuel inlet pipe that im blowing into delivers fuel the other side of the diaphragm and with the rip its then coming out the hole.
I suppose ive answered my own questions as if the pipe was this side it would be a direct supply to the hole.

I will need to pop off another carb i have to try & see if the issue is fixed.
