Can 2 cylinders fire at the same time?
In two-cylinder engines, the cylinders can either fire simultaneously (such as in a flat-twin engine) or one after the other (such as in a straight-twin engine). V8 engines use various different firing orders, even using different firing orders between engines from the same manufacturer.
Why engine cylinders do not fire at the same time?
The point of having multi cylinder engines is to NOT have them fire all at once but have equal amount of time between the firing order of each cylinder during the rotation of the crankshaft to generate a smoother power delivery.
Can a mechanical problem cause an engine to misfire?
Many people also don’t realize that an engine mechanical problem can cause a misfire. Each cylinder inside the engine contains a piston that must compress the air/fuel mixture for complete combustion. And when the piston is moving upward, the cylinder must remain completely sealed off to create adequate compression.
How to troubleshoot a 2 stroke engine with no fuel?
2 Stroke Engine Troubleshooting – Spark But No Fuel. As you read above this is assuming you have checked the basics, you know, gas is on, gas in the tank, choke is on. One quick check you can do is to pull the fuel line off your carburetor, turn the gas on for a second and see if fuel is flowing out the fuel line.
What causes a car engine to lose compression?
There are several causes you can eliminate if your cylinders are losing compression. One possibility is a blown head gasket. The head gasket connects to the cylinder head at the top of the engine. If there is a problem, you’ll notice a gap between the cylinder and the head, and gas will escape the cylinder, leading to low compression.
What happens when a catalytic converter is misfiring?
When a cylinder misfires, it can cause a cylinder’s worth of hot, unburnt to fuel enter the catalytic converter, melt the ceramic material inside. As the inside of the catalytic converter heats up it can start to break apart, plugging the exhaust, which causes problems to keep cascading. But catalytic converters aren’t the only concern.

Where does the fuel and air mix go in a two cycle engine?
The reason is that the fuel and air mix enter the crankcase on a two cycle engine and do not go directly to the cylinder, the fuel and oil mix coat all the internal components of the engine and then when the piston comes down, pressure in the crankcase forces the mix into the combustion area.
What happens when you have air leak in 2 cycle engine?
If you have an air leak, you will draw extra air into the crankcase, bypassing the carburetor and then it can flow back out of the leak area and not enter the combustion chamber. Air leaks into the crankcase of a 2 cycle engine can cause a big headache.
Why is the air not going to the cylinders?
When I put a piece of plastic in front of the carb intake and pull, the plastic is drawn in. Since the air leak must be small enough to still pull air in through the carb and since the only place for that carb air to go is the cylinders, why is the start spray not poping or puffing or something?
