Pretty sure that's a 4 stroke and you have a separate place for your oil.
A Troy-Bilt 21 inch cutting blade 190cc 6.7 HP engine does not need an oil and gas mix. It is a 4 cycle engine which keeps the oil and gas separate for maximum efficiency.
The engine would stop running. You would need to drain the gas tank. If the engine has been allowed to run since the diesel was added you would also need to drain the fuel line.
I assume you mean oil and not kit. If that's the case then no.
A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
NO !! 2 stroke fuel is gas and oil mixed. unless you took it out of a oil injected 2 stroke with i doubt. a 4 stoke engine (car) doesnt need any oil in the gas. (NOT GOOD) you can put 2stroke fuel in an unleaded engine the 2 stroke has oil added to it but will still burn off.most people put 2 stroke in by accident or in an emergency when none other is available,such as running out of fuel.the amount added would be minimal and would be so diluted it will do NO damage to your engine. the GAS used in 2 stroke is same as any other gas , just has small amount of oil added
need engine size. 24 to 35 depends on engine,
Not really sure what you're getting at. If your lawnmower engine is a 2-stroke then you need a mixture of oil and gas to run it.
An engine will stall when you give it gas if it does not have the correct mixture of fuel and air. This is controlled by the carburetor or throttle body and may need adjustment.
if it is a 50cc engine or less no u do not need a licence
Need to know what it is.
In order to use less gas, the size of the engine is reduced, but it also reduces its power. A turbocharger is then added to increase the power of the engine.
You'd need to swap in a gas engine. A lot of people believe that the Oldsmobile 5.7 LF9 diesel was a gas engine converted into a diesel - this is simply not true.
