Whether you use a traditional hand-pushed mower or a riding model , work through the list before even thinking about a replacement.
If you use a fuel-powered lawnmower, you may have trouble getting it started after a long and cold winter. The problem may be related to the spark plug. Or a blockage in the fuel line may be starving the engine of gasoline. If you run into problems getting your lawnmower ready for spring , try the following:. These components in and around the engine can become clogged with a range of substances — starving the engine of either fuel or air.
Drain the old oil fully before adding the new. Ideally, this should be done once a year — just before the first lawnmowing job if the year.
Again, go through the steps listed above if your lawnmower starts then dies within seconds. This could be down to old fuel left in the tank over the winter. Doing so can draw air into the engine, causing accumulations of gum and varnish. This specially-formulated fuel additive stops gasoline from breaking down into its component parts. Run the engine for a few minutes before trying again. For the best results, add some fuel stabilizer to every fuel can — particularly during the final weeks of fall.
After being serviced over the winter my mower did well for the first 3 cuts of the season. An engine that's getting gas and not starting probably has a flooded carburetor or cylinder soaked with gasoline. Often your nose can make the diagnosis: Flooded engines reek of unburned fuel. Park the mower on level ground, and wait about 15 minutes for the gas to evaporate. Then try starting it again, with the choke off. Freshen the fuel. If the engine starts and quickly stalls out, the gas may have gone bad from sitting around too long.
Siphon out the tank, and add new gas. Take the old stuff to a hazardous waste recycler; dumping it anywhere else is illegal.
The important thing is to check or change one thing at a time and see the results. Question: I replaced the magnetic pick up in my mower, but there is still no spark. What can I check next? Answer: Replace the spark plug, check the ground of the pickup or that the ignition coil is making contact with the engine block. Also, check the spark lead and make sure the kill switch isn't shorting out the primary when the throttle is set to the run position.
I presume you mean you placed it on its side? It's possible that oil ran out of the engine into the carburetor and fouled the air filter. Remove the air filter housing and check whether this has happened. You can wash sponge filters in detergent, squeeze dry in a cloth and add a teaspoon of motor oil and massage it through the foam.
Paper filters may need to be replaced. It's possible either that petrol flooded the carburetor, so allowing the mower to sit for a while for it to drain and evaporate before attempting to start could help.
I place my mower on it's side, it starts but for seconds only, what should I do to repair it? Thanks in advance. It could be several things including a battery that wasn't fully charged when you bought it so starting took a big chunk of charge out of it.
If it's brand new, hopefully it came with a warranty, so it's best not to meddle with it. The battery voltage should be 13 volt or so for a fully charged battery, so if it's less than 12 volt there's some sort of charging issue. Overfilling shouldn'treally prevent it from starting.
Fuel flow is regulated by a device called a float bowl, located under the tank. This pretty much acts like a toilet cistern, the reservoir keeping fuel at a constant level, irrespective of how much fuel is in the tank. If the inlet valve from the tank isn't working properly in it though, maybe fuel could overflow into the carburetor, flooding it Try removing fuel and leave the mower to sit for a while for any fuel in the carburetor to evaporate. Not sure how you'll remove excess fuel form the tank.
Sometimes I use a thoroughly washed out pump from a handwash bottle that produces a jet and squirt fuel into a container don't use a spray type version! Possibly, but you need to consult the manual that came with the mower or contact the store for further details. New mowers are also normally sold without engine oil so it doesn't leak out if a boxed mower ends up upside down during transit so you will more than likely have to add that also.
Check the dipstick. Very useful! It's good to have an article like this to reference when my small engines won't start. Home Appliances. Air Conditioners.
