If the fuel is contaminated with water the mower will most likley not fire at all. you more than likley have a pulsa jet carb on your mower. you will need to get a rebiuld kit that has a diaphram in it. replace the diaphram and re install carb. this will take care of your problem. the diaphram pulsates under vacum created from your intake and pumps fuel to your engine. 1 way to test this theorey is tie your engine brake handle back. then start your engine after a few primes. when it fires hurry and give the primer button another push or two. If the mower continues to fire while priming the diaphram is bad!
I dont understand the pulling the button - do you mean push the primer button - if you mean primer button it sounds like the high speed jet in the carb is dirty and needs service- you can attempt to start and once engine fires have someone continually push primer to keep running it ma clear the blockage - did You check the fuel tank for any water ?
