It means the engine has been fed too much gas. If you depress the gas pedal on a car or truck many times before you start it, the same thing will happen. A gas engine, whether it is a small lawn mower engine or a truck's engine works the same. It needs a certain ratio of gas and air in order to create the explosion in the piston chamber that makes the engine work.
it needs gas
you mean a lawn mower right.. if so no
If your lawn mower is pulsating, it may mean that it is not getting enough fuel and the carburetor may need cleaning.
If you mean the engine will rev up and down as it is running, it has been my experience that a dirty air filter is a cause of the fluctuation.
it is a fancy way of saying that it is an automatic transmission for the Lawnmower
its burning oil :(
If by "overloading" you mean flooding (too much fuel), two reasons are (1) the carburetor needle valve is "wide open" or the float is stuck in the open position.
It could be that the mower was tilted on its side or that the rings are bad.
Oil burning
In the context of a mower, "160cc" refers to the engine's displacement, which is the total volume of all the cylinders in the engine measured in cubic centimeters (cc). A 160cc engine typically provides a good balance of power and efficiency for small to medium-sized lawn mowers, making it suitable for residential use. This measurement can help determine the mower's cutting capabilities and overall performance.
Not sure what you mean by "idle funny". If you mean the engine revs up and down while it is idling, the problem is most likely a dirty/clogged air filter.
If you mean the rotary mower, that would be Lawn-Boy in the early 1950's. Then owned by OMC who was looking for another use for their engines. The original was a single cylinder outboard motor converted to air cooling.
