T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed. With the chainsaw still running, take a screwdriver and turn the L screw clockwise. Keep turning it until the engine stops, then turn it clockwise until it starts to run again. This is the idle speed setting. – When the idler pulley is fully extended, the T and L screws are turned in opposite directions.
T screws control the amount of fuel that goes into and out of the carbs. When idle is reached, both screws will be turned back in the same direction. If you don’t have a T-screw, you will need to use a small flat-head screw driver to turn them in one direction or the other, depending on the type of carb you are using.
For example, if you’re using a 4-valve carb, and you want to make sure you have the right idle setting, use the flat head screw drivers to rotate the screws in either direction until you reach the correct setting for your carb.

What size chain goes on a Husqvarna 450 Rancher?
This chain saw chain is designed to be used with the Husky 450R chainsaw. It is made of high quality steel and is available in a variety of lengths. This chain will work with any chain that has a 1/2″ pitch.
How do you adjust the H and L on a Husqvarna chainsaw?
When the saw is rotating up to speed, the “H” screw is used to adjust the saw\’s RPMs, while the “L” screw is used to control low throttle operation. The third screw is used to set the idling speed when the saw is running and when it’s rotating down to idling.
You can also see that the screw labeled “A” is the same as the one on the left, and the other two screws are labeled with the letters “B” and “C” respectively. This is a common mistake made by people who don’t know the difference between the two types of screws.
It’s important to know which screw you’re using, because it will affect how much torque you’ll need to apply to the blade to get it to rotate at the correct speed for your application.
Where is the idle screw on a Husqvarna chainsaw?
The manual for the Husqvarna 51 states that the high-speed screw is labeled “H”, the low-speed screw is labeled “L” and the idling-speed screw is labeled “T”. Remove the chain tensioner from the motor and remove the two screws that hold it in place. Remove the four bolts that secure the pulley assembly to its mounting bracket. Unscrew the three screws holding the belt tensioning pulleys to their mounting brackets.
Pull the tensioners out of their mounts and set them aside. If you don’t have access to a drill press, you can use a pair of pliers to pry off the top and bottom bolts on each motor. You’ll need to do this carefully, as the bolts are very sharp and may cut you if you’re not careful.
Be careful not to cut yourself or your tools. the bottom bolt on one motor is marked “B.” Remove this bolt by prying it off with a small flat-head screwdriver or similar tool. The top bolt is also marked with the same marking, but it’s not necessary to remove it to get to it.
Are chainsaw chains directional?
The direction of the chainsaw blade is always the same regardless of the type or model of chainsaw. The sharp edges of the blade should always face the opposite direction. The sharp edges are facing the direction opposite of the chainsaw’s rotation if you check from the top. The left chainaw is rotating counter-clockwise while the right one is turning clock-wise. This is the reason why the blades are pointing in opposite directions.
How tight should your chainsaw chain be?
A properly-tensioned chainsaw chain needs to be tight enough that you can’t pull the guide bars out of the way with your hands. If you’re using a chain that’s too loose, you’ll need to tighten it up before you start to use it.
You can do this by loosening the tension on your chain and then tightening it back up after you’ve used it for a few minutes. If you don’t have a tensioner handy, just use a pair of pliers to loosen the slack.
