They either overheat, (usually caused by debris under the engine cover which is blocking the cooling fins) run low or out of oil, break an internal part in the engine or just get wore out from age. You could also have a belt or pulley problem not letting it turn..
Two-cycle lawnmower engines are rare.
both are limited by maximum piston acceleration , which occurs at higher revs in shorter stroke engines
yes.... as with almost all engines. let it sit for a day
Most small engines use 30 weight non-detergent type.
A self propelled pushing lawnmower might stop operating because you may have gotten something caught in the blades. Or the operator might haver run out of energy. If a power mower. A possible reason. If you don't check the oil, you might have run out. Once the engine gets hot enough, without oil, it will seize up. This will render your lawnmower useless. Whenever you use your lawnmower, just like checking the gas, check the oil also. As running out of gas will stop the lawnmower temporarily, running out of oil can stop it forever.
Lawnmower engines are reliable devices, and should not require any adjustment. The main thing that should be adjusted or replaced is the throttle cable length and position, and the governor springs.
I found parts for eagle star at BARRETTE'S SMALL ENGINES www.SmallEngines.ca
I think it is a 2.5 horsepower engine. There are 4 oil formulas for Kawasaki lawnmower engines. I recommend you use the correct blend as stated in your owner's manual.
This can not really be done. First of all, lawnmower engines oil systems are designed to be vertical at all times. Second, it would be very hard to mount the motor. They also have no clutch. You can by lawn mower type engines like on the old classic mini bikes and go carts which will work because they are horizontal shaft type motors. You can by them on small engines warehouse. com
you take a jack and jack it up.
no because there i no lubrication in it and the engine would seize after a little while
If the lawnmower is not electric powered then is is probably operated by an internal combustion engine (petrol or diesel. Oddly enough, very early lawnmowers were steam powered, which means they were examples of external combustion engines.
