Hi all
can anyone help, I have a Mountfeild hp474 petrol mower I bought this off a friend and after getting it home a noticed there was engine oil coming out of the filter, I had taken off the carb cleaned it all with new filter and plug and everything was good after then then over the past few weeks she has been running not right, fires up no problem runs fine at fool throttle/choke, once it has warmed up and oush the throttle to the rabbit it starts to hunt and struggle a bit, it can then start to do the odd misfire and when it does there is a puff of black smoke from the exhaust, it has a LHP16 carburettor and I have changed the oil, fresh fuel, spark plug(Briggs&Stratton) new gasket between carb and filter box, new filter and new rubber ring gasket. There is nothing more I can change and the carb is none adjustable. Can anyone shed any light on what it could be
Thanks
