Recent Service, now engine is very spluttery

If you are talking about the old carb then apart from the diaphragm being work out so not strong enough to suck the fuel from the bottom you also get cracks in the pick up tube or plain blocked filters .

No this happened on the old and new carb, can it be anything else? Thanks

Was the carb bought from a mower shop or genuine on line pars retailer or a $10 ebay/ amazon lucky dip ?

genuine one. Like the one it replaced

The fact that the problem is the same with both carbs & responds to variations in the height of fuel in the tank points to a pump failure of some sort.
The most usual tank failures arise from the tank warping or from corrosion around the diaphragm.
Once I have seen the threads pulled up on an alloy tank but to this day can not work out how the owner managed that .
So slip it back off and run a strait edge across the mating surface .
