Clean the air filter (foam type) in warm soap water then apply some oil soaked in, it will smoke afterwards for a short time. Or possible minor adjustment too the mixture screw on the side of the carburetor spring loaded. Allan

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.

I had the same problem, Tilt the lawnmower on it's side air filter facing up and remove air filter cover and air filter then remove the fuel bowl underneath the carb; then clean the fuel bowl with some gas and a clean rag. For the next step be sure to aim blower tip at target then look away before pressing trigger, this will prevent gasoline form getting into your eyes.Take an air compressor and carefully clean out the carb where the flap is and the tube where the fuel float that would rest inside fuel bowl is. Leave on side install everything back except for air filter and cover. Then pour a little gas in the carb to prime it, lay the lawnmower back on all 4 wheels and try to start.

Your carburettor needs cleaning.Remove it and loose it down, wash it in kerosene and blow it out well with compressed air. Hope this helps. Stephen

Start by replacing the fuel filter and connecting hose at the leak point. It is important to use "fuel hose" and fuel hose clips - which are different to standard hose clamps.

If you have problems with mice - use a steel braided fuel hose - as they can't chew through these ! -

Try takeing the air filter off,shake well,and reinstall,if still stalling remove air filter and leave off and see if it still stalls?? Let me know and please rate. thanks

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.
