Hi, first you'll have to change the air filter and the spark plug. now, go buy some hi octane gas. drain the old gas and put the fresh gas in. if this don't solve your problem please write again.

How do I change a worn Carburettor Gasket and Diaphram on a SP470 B&S Engine on my Mountfield Lawnmower? I'm good at DIY. The engine is hunting and running erratically.


Hunting and erratic operation are signs of air leaks or diminished fuel flow at WOT settings.

If this mower is running a vacu jet style carb with a diaphragm you simply take off the air cleaner, the vent tube, and then the four screws holding the carb on the gas tank and after the carb body can be lifted remove the throttle linkage so you can flip over the carb and pull the main jet and clean the inlet screens.

Draper petrol lawnmower wont start


Check the fuel...most often stale fuel creates havoc...YOU MUST FLUSH THE TANK donot add to old crumby gas, YOU MUST clean out the carb(remove the fuel bowl and carb spray all the tiny openings,orifices, check the air filter, check the oil, Add NEW fresh fuel, and hit with a quick spray of starting fluid just prior to restarting...should run out well.

Caren,
Drain the fuel completely if it is older than 1 week. Make sure you undo the bolt at the bottom of the fuel bowl to ensure all old fuel is drained. Refill with fresh fuel (premium unleaded) and try again. If it still does not work then remove the spark plug and rest it on the metal of the mower while still attached to the silicone ignition wire. Have someone hold the cut out bar to the handle (as you normally would to run the motor) and pull the cord. You should see sparks being emitted from the spark plug. (Make sure there is no fuel nearby) If you cannot see any sparks then replace the spark plug with a new one and repeat this process. If you still cannot see any sparks being emitted after attatching the new plug to the silicone wire, resting it on the metal of the mower, and pulling the cord to start it as you normally would, the mower will need to have the resistor and capacitor checked by a professional repairer as no spark is being generated.

Good luck.
