my 5.5hp b&s Quantum engine won't stay running. It will run for a couple second after pressing the primer three times. I've replaced the filter and it has new gas.
Would recomend that you replace the spark plug first,and if that does not improve it sounds that the diaphram might need changing.Sucking air in with the fuel causing engine to stall.
