Well on my tomos 50cc dirtbike it's 3.0 ounces of oil per U.S. gallon but that's on mine I think that should work and on my tomos it's a 50:1 fuel mix ratio
what is the fuel and oil mixture for a kx 250, 2 stroke
No, the intake stroke pulls fuel-air into the cylinder, the compression stroke squeezes (compresses) this mixture into a small volume.
At the top of the compression stroke. That's the point at which the fuel/air mixture is under greatest pressure.
it is oil injected
40:1 is the mixture of gas to 2 stroke motor oil (only)
Briggs and Stratton made almost exclusively four stroke engines. There is no fuel oil mixture for a four stroke engine. Are you sure you have a two stroke engine by Briggs and Stratto? rhg
straight fuel/4 stroke
In the power stroke:Intake stroke --- draws the fuel mixture into the cylinderCompression stroke --- pressurizes the fuel mixturePower stroke --- ignites the fuel and causes the product gases to push against the pistonsExhaust stroke --- expels waste gases from the cylinder* PIE C is a good way to remember it. Or C PIE. *

Not sure what you are asking here... But here goes: Stroke 1: Intake stroke. The intake valve is open, and fuel air mixture is sucked into the cylinder as the piston moves down. Stroke 2: The intake valve is closed, and the fuel air mixture is compressed as the piston moves up. Stroke 3: The power stroke. The compressed fuel air mixture is ignited by the spark plug. The resulting explosion forces the piston down, providing power. Stroke 4: The exhaust valve is opened, and the spent fuel air mixture (now exhaust) is pushed out of the cylinder by the rising piston. Repeat indefinitely...
The fuel mixture for a Yamaha 40 hp 2 stroke outboard engine is 50:1, gas, oil mixture. You should use new gas when you get the engine ready for the season.
the air mixture i.e air and the fuel mixture entering the clyinder during the piston moving from top dead center to bottom dead center this is known as intake stroke
