The throttle stop had worked loose and would drift from low to high while running. Reset and tightened.

Hi, I have a Mac-3200 and need to know where to set the 3 carb. screws at. T, low and high I don't have a manual Thank you. Z-man

Most guys adjust them 'by ear'. Warm up the saw (hopefully you can get it to start), and set the high speed by opening the screw until it sounds like it is 'burbling' at wide open throttle. DO NOT adjust until it is screaming at its highes attainable rpm !!!! If you do, the mixture will be so lean it will damage the saw under repeated heavy load. Leaving it 'burble' at WOT (wide open throttle) will ensure that proper lubrication will be available in the cut. Under load, the burble will disappear and the saw should pull strong and not overheat, damage the piston or score the cylinder wall.

Next set the low speed screw until there is no hesitation in rpm increase when the trigger is pulled. Some suggest setting the low speed first then the high speed so you may have to readjust the high speed once the low speed is done.

The idle screw should be adjusted to where the chain is NOT rotating the guide bar at idle. If it continues to move, the idle is too high.

Mcculloch MS 1415 electric chain saw throws chains

I had a saw that did that and found my blade the chain runs in was bent. Another problem was the groove the chain goes in had a gouge that did not look like much but was just enough to throw the chain. Also check the drive sprocket and make sure it lines up with the groove in the blade the chain runs in.I replaced the blade and its ok now.

Carburetor adjustment

Generally if you will set the screws about 1 1/2 turns an choke it on start it will go if everything else is ok. The set screws to proper idle an high speed run. Those are very cranky saws so take a few aspirins it might help. Lol

Set both the high and low speed screws from lightly seated to 1 1/4 turns out. This will give you a rough setting that will allow the saw to start and idle. Set the idle screw to where the chain just stops moving at idle.
With the saw warmed up adjust the low speed screw out until the saw smokes a bit and acceleration is sluggish. Bring the screw in small steps until the hesitation is gone from the may need to adjust the idle again after this.
Now hold the throttle wide open and while it is wide open adjust the high speed screw in until the noise becomes smooth and the saw "sings". Do not leave it at this setting as it will burn down in short order. Once the saw is singing back the screw out until you can hear the saw's tone "roughen"....then back the screw out a tad more for good power / fuel under load.
That's it in a's a good link also...

I need to see a diagram where the chain oil feeder is on a mcculloch eager ****** chain saw

Remove the rear case cover which exposes both tanks, the oil pump and the short coupling line that goes from the pump to the bracket that the bar assembly bolts to. If you remove the bar and chain, that exposes the side port that is coupled to the hole in the bar that distributes the oil to the chain. There is a screw in the case back near the bar that adjusts the oil volume. When the bar/chain is off, clean the side port on the engine, and start the engine. It should ooze out oil when running at moderate speed. Clean the oil passages in the bar end including the two small ports that go out to the chain groove on each side. After everything is back together, run the saw bar tip at speed near a piece of cardboard for several moments--it should throw off a thin line of oil. Hope this helps!

I can't get the idel set on the McCulloch Mac130 chain saw. It runs wide open. When you try to idle it dies out.

Try turning the L needle CW to stop (lightly), then back out CCW 1-3/4 turns. Turn the idle speed screw CW about 1 turn. Start the engine and let warm up. Set the idle speed screw so that the engine keeps running but doesn't pull the chain. Turn the L needle CW until the engine runs fairly smoothly, yet allows the engine to 'follow the throttle'. Make sure the H needle is adjusted at full speed for 4-stroking, but immediately 2-strokes when starting to cut wood. If the above idle mix (L) adjustment doesn't help, you will likely need to clean the idle jets within the carburetor. Hope this helps!

Where is the air filter on a homelite super2?

If you remove the top plastic cover on top of the saw, you will find the air filter under that cover.

No top end power

Have a set of really small screwdivers ready. First, make certain the saw hasn't set up a season and gotten all gunked up. If it has, take off the air filter and wash the carb out with carb spray cleaner. You may have to replaces all the fuel lines. Once it has fresh gas in it, and you can smell the fresh gas by pumping the bulb til the shellac smell is gone, take off the air cleaner and fire it up, even if you have to use starter fluid spraying a shot into the carb. (You'll probably need a new plug by now).

When it starts to run, hold it at high throttle and adjust the high speed mixture screw to the right until it smooths out, or if it gets worse, to the left. Once it runs smoothly, keep turning til it begins to stutter, then turn back a half turn.

After you get it to run ok at high speed, you'll need to adjust the low speed until it starts and revs up quickly.

Poulan 2450 wont start

After warming up the engine at part throttle for a couple of minutes, clear it out with a 3 second burst. Then idle the engine.. If the chain rotates, turn the idle speed screw to the left (CCW) until the chain stops.
Turn the LO NEEDLE slowly to the right (CW) to find the fastest engine speed. If this causes the chain to rotate, repeat idle screw adjustment to stop the chain from rotating.
High speed (with throttle wide open). Set needle 1-1/4 turns open, checking for smooth acceleration by opening the throttle wide for 3 seconds. If the saw stumbles, turn needle to the right (CW) 1/8 turn @ a time until smooth acceleration is obtained. Try a saw cut to see if adequate power is available. Continue making 1/8 turn adjustments (CW) until saw shows a power drop when asked to cut. (This indicates too lean a mixture setting.) Then, from the setting in step 3, turn the HIGH NEEDLE 1/4 turn to the left (CCW). Check the cutting ability of the saw again. This should be the best setting for your particular altitude, temp. and humidity conditions.
To pre-set before initally starting the saw, turn LOW and HIGH and IDLE screws in gently till each one just stops. Then turn each out (CCW) 1 - 1 - 1 1/4 turn.
Hope this is helpful. Try Select the "Tech. Guide"
Good luck and God Bless.
