Took me a couple seconds to realize it was running backwards and shut it off but it ran good with no strange noises. I’ve heard of a saw running backwards, I don’t remember what would cause it to do it but that particular saw would do it fairly often. Also I’ve heard about people stalling a Detroit 2 stroke diesel powered truck on a hill and have it start running backwards.
Yes, 2-stroke engines will run backwards…not very well, but they will run backwards. Bumped the starter button one day, popped it into first gear, let out on the clutch and almost went over the handlebars as it lunged backwards throwing rocks between my feet!!! Also had a Detroit Diesel run backwards once. All I can say is if you do happen to get a saw to run backwards……DON’T pull the starter rope with it running!!
why would a chainsaw run backwards Related Question:
Does a chainsaw run clockwise?
These blades have two edges, one of which is sharp, and the other one is dull. A chainsaw blade always rotates from a clockwise direction. The direction of the chainsaw blade is always the same regardless of the type or model of chainsaw. So the sharp edges of the blade should always face the clockwise direction.
Which way does a chainsaw engine turn?
Chainsaw chains rotate in a clockwise direction, so the cutting edges should be facing away from the engine and to the right, on the top of the chain.
Can 2 strokes run backwards?
A two stroke can run backwards because the event timing (intake, exhaust, etc) other than ignition is controlled by the piston, and the piston knows only that it’s going up and down, not which direction the crank is turning.
How do I know which way my chainsaw chain is?
Getting the chainsaw chain direction right is very straightforward. When viewing the chain at the top of the bar, the cutter must be facing towards the tip of the chainsaw bar. When looking at the chain on the bottom of the bar, the cutter must be facing the powerhead.
Why would a 2-stroke motor run backwards?
It was common for old 2 stroke engines to spin in a different direction. They do not have valves or cams, so they do not have a clockwork mechanism for synchronizing. It usually happens when the ignition timing is advanced enough to cause the engine to spin in the opposite direction just to synchronize.
What causes an engine to run backwards?
A lack of lubrication and filter intake air results in engine startup getting backwards because of rebound of compression from bumping the starter motor.
What happens if you put a 2-stroke piston in backwards?
On a 2-stroke, there are pins in the ring grooves that keep the rings from rotating.otherwise they would catch in the edge of a port and cause a lot of damage. Obviously you were lucky that the locating pins on the CR piston did not travel across any ports even when put in backwards.
When should I replace chainsaw chain?
Once the wear markers have been met it’s essential to replace the chainsaw chain. Filing past the wear marker will greatly reduce the chain’s cutting performance, and increases the risk of the tooth breaking off. Ideally you should reach the tooth and depth gauge markers at roughly about the same time.
How long should a chainsaw blade stay sharp?
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
Can you over tighten a chainsaw chain?
There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don’t over-tighten the chain as this could cause it to break.
What are bow chainsaws used for?
A modern bow saw is a metal-framed crosscut saw in the shape of a bow with a coarse wide blade. This type of saw is also known as a Swede saw, Finn saw or bucksaw. It is a rough tool that can be used for cross-cutting branches or firewood, up to six inches (150 mm) in diameter.
