Poulan chainsaws come pre-adjusted from the manufacturer, but due to various reasons, you may need to readjust the carburetor. Don’t worry; modifying the carburetor isn’t rocket science. We’ve curated the perfect guide for you to follow!
Tools Required For Adjusting The Carburetor
The tools you’ll need for recalibrating the carburetor can be found in almost every household. You’ll need a screwdriver for unscrewing.
Lukewarm water and soap are required for cleaning the air filter. You’ll also need a scrubber or a brush. Keep a pair of gloves on the list, too, if you don’t want your hand to get all greasy during the process.
Adjusting The Carburetor
Step 1
For adjusting the carburetor, you must work in an isolated surroundings as the saw may spin during the process. In order to avoid accidents and injury, place the saw on a completely flat bench and make sure that no objects are in close proximity to it.
Step 2
Open the cover of the air filter by undoing the three retaining screws placed on it. For unscrewing, choose the correct sized screwdriver. After removing the cover, take out the filter carefully.
Step 3
Clean the air filter thoroughly. For cleaning, it’s best to use lukewarm water rather than cold water. But be careful the water isn’t boiling hot, or it may damage your equipment. You can use any brand of soap or dishwashing liquid.
Scrub the filter with a brush rigorously to get rid of any grease or soot stuck inside it.
After you’re done cleaning the filter, make sure it’s completely dried.
If the air filter is filthy beyond repair, you’ll have to get a new one.
Step 4
The saw’s spark arrestor is located behind the muffler. Remove the cylinder cover to get access to the arrestor and take it out. You’ll need to clean the arrestor’s dusty screen with a wired brush. After you’ve cleaned the screen, put the filter and the arrestor back into place.
Step 5
Turn on the chainsaw. Check if the engine can stay powered on without interruptions. If it can’t do so, turn the screw marked ‘T’ clockwise with a screwdriver. Rotate the screw counterclockwise if the machine becomes idle very quickly.
Find the correct placement where the engine runs properly and continuously without engaging the chain.
Step 6
For adjusting the high speed screw ‘H’ or the low speed screw ‘L,’ follow the guidelines mentioned in the manual. While adjusting the screws, you can track the speed of the engine using a tachometer.
