A four stroke engine is like the one in most cars today.
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.
The flywheel smooths out the pulse of the power stroke and its inertia allows the crank shaft to continue rotating to bring the next piston into position to fire. Look at it like this: You could pedal your bicycle with one foot if the pedal had a flywheel on it.
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
Look up Gamma,or a RG500.
You cannot see the crankshaft without dissembling the engine. It is located inside the engine, lower part of the engine block. Pistons and connecting rods are bolted to the crankshaft.
Floppy
look at the front (with the pulleys) of th engine
it looks like a black square
crank shaft sensor or(ckp) is look like a simple sensor.its color is black.its lenth is two inches.GILL G
well the person can just be there and it will look like a seizure almost, you most likely wont realize that it is a stroke because one minute the person can be fine and the next they are out of it.
depends on what kind of sensor you are looking for? Cam shaft, coolant temp, Mass airflow, oil pressure, etc?
