Fuel in the oil is most likely down to fuel getting past the diaphragm in the fuel pump so could that be down to the old pump ?
Have you checked that you still have a spark , preferably when there is no fuel sloshing around ?

Yes check for a spark using an old plug. It could be that the points have failed and not producing a spark hence why the plugs are soaked in petrol

Hi thanks for the info.but yes there is a spark at the plugs.when I dried the plugs out and got all the petrol out of the carb,the car ran(Rather lumpy as if only on one cylinder)for a few minutes,but then just stopped and it was all flooded again??

OK so if the float itself is new then is it free moving, set to the right height and the needle cut-off valve in the carb lid working properly

That would be my next port of call, check the needle. vibrations over time could've opened it up. Screw it in all the way then turn it back - I think 1 and a half times. Oh and check the chokes all ok aswell

Thanks you guys,I will try that later on.I will remove the card and check it out.......

Hi guys..tried all those (thanks) no different,asked local carb specialist(Weberman) says the carb needs complete strip down,but.....as the carb is a Polish 30/S2H there are no carb kits available so the only answer is a new carb!and....as the Polish one is not available anywhere a Weber would have to be used at a cost of wait for it.....£300 plus delivery and VAT.surely this cant be right...or IS IT???

Search eBay for "fiat 126 breaking". There are a couple of BIS on there and you might be able to get the complete carb for a few quid.

Thanks for that.unfortunately they were the wrong ones,mine apparently is a Polish carb numbered 30/S2H and they are Webers...
