wouldn't it run on gas or am i wrong
No, its need fuel
it will probably explode or it will burst into flames either or its bad
A small push mower. A Lawn Boy Mower is best for hilly slopes because they don't have any oil in the bottom like a 4 stroke - the 4 strokes run out of oil if you run them on a hill, but the Lawn-Boys are 2 stroke.
Build a ramp. Get a good long run at it.

It won't run on pure deisel.
Oil is a lubricant that helps to keep an engine running. If a person runs a lawn mower without oil, the mower will run, but it will cause problems like stalling out, or worse. +++ Its engine will run, but only for a very short time before seizing, probably ruining it.
If the lawn mower is run without oil, the connecting rod bearing will heat and score, or even "weld" to the crankshaft, causing major damage.
If you are talking about the bulb button it is a primer to get gas to the carburetor if the mower has not run for awhile. Usually not needed to restart a warm mower.
You may want to check your manual for your particular mower. I used 30 weight oil in my old mower circa 1978.
Is this even a real question? Seriously, man. What does your mower run on? Hopes and dreams?
