Mountfield With B & S engine keeps stalling?

Hi dave I have the same problem writhe same lawn mower from the same shop. I have to push the petrol primer button on the side to keep it going with would suggest that petrol is not being sucked or pumped through at all. Do these things have petrol pumps. I initially thought that it was a fault on the carburettor which I haven't explored yet. Will mean a strip down though and a clean. Sorry cant help really but if u find out let me know.
