Often asked: How To Adjust The Carburetor On A Poulan Chainsaw?

How do you adjust the idle on a Poulan Pro 42cc chainsaw?

If the engine sputters or stalls quickly, the idle speed is too slow. Turn the T-screw one-quarter turn clockwise and restart the saw. If the saw idles too slowly, adjust the T-screw another quarter-turn clockwise and check it again. Repeat this process until the saw idles without stalling.

Why does my Poulan chainsaw dies when I give it gas?

The fuel filter might be clogged. A clogged fuel filter is often caused by leaving old fuel in the chainsaw. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and cause the engine to stall.

Why does my chainsaw dies when I give it gas?

Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle. If the filter becomes clogged, not enough fuel will reach the engine for it to run properly.

Why does my chainsaw bog down when I give it gas?

If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.

How do you adjust the high and low on a Poulan chainsaw?

High and Low Speed Adjustments Start the chain saw as you normally do and let it idle, making sure the chain does not touch anything. Insert a small flat-head screwdriver into the idle speed screw and turn it clockwise to increase the engine speed if it idles too slowly.

Can’t get my Poulan chainsaw started?

If your Poulan chain saw won’t start, the first thing to check is the fuel. Then turn the saw on, hold it firmly and pull the start rope in short, brisk pulls until it starts. If it doesn’t start within 15 pulls, the spark plug is likely wet-fouled. Remove it and check for moisture on the electrode.

How do you adjust a high and low carburetor?

Locate the two fuel-adjustment screws on the side of the carburetor. One will be labeled “Hi” and the other “Lo.” The “Hi” screw regulates the engine at full throttle and the “Lo” regulates the fuel when the engine is idling.

What is the T adjustment on a Poulan chainsaw?

The screw on top — marked “T” — is for adjusting the fuel mixture while the engine is idling. Of the two underneath it, the one on the left is for adjusting the mixture when the engine is running a low speed, and the one on the right is for making the same adjustment when the engine is running at high speed.

Why does my chainsaw only runs on choke?

If your chainsaw only runs with the choke on, it is likely an issue with your carburetor. If the carburetor is plugged, the engine will be starved of fuel and will not run. However, if the engine is plugged, the choke will pull more fuel through the carburetor’s idle circuit and allow it to run.
