SOURCE: chainsaw idles but bogs out and dies when given full throttle.

First thing,
Check the air filter, once checked, & clean/replaced,
Adjust timing.
This is a very easy job to undertake on small petrol engines.
1: adjust the gap between the contact & the magneto,
2:Or adjust the space on the tip of the plug.
So simple.
Fixed'Ya!

Hi 1tgriffin,
My name is Dennis and I hope that will serve your needs.
IDLE ADJUSTMENTS:
There are three adjustment screws on the carburetor labeled
H (for High speed MIXTURE)
L (for low speed MIXTURE)
T (for idle SPEED SETTING)
They are located just above the primer bulb. If your saw floods so soon in the starting process the idle mixture setting can be set too rich and the speed may be set too slow. Remember the chain will not move when the idle speed is set correctly with a WARM ENGINE!
Adjust the idle speed to just below chain movement WITH A WARM ENGINE this is just below the activation RPM of the centrifugal clutch. Let the engine run at a higher speed than idle until it is warm -- 3 min -- you may have to keep goosing it until then.
Please don't exceed the limits of the plastic limiters when making adjustments.
If you haven't adjusted the mixture screws you may just have to adjust the idle speed and that can start my turning that screw all the way in to the stop and then back out 4-1/2 turns for a good place to start. FAST IDLE -- Adjust the speed until the engine runs with out the chain moving. Adjust clockwise to increase speed. C clockwise to decrease engine speed.
Accelerate the engine and if it stumbles and makes too much smoke it's too rich turn the
LOW SPEED MIXTURE (in) clockwise in 1/16 a turn increments NO MORE at a time because a two cycle needs to run at a setting for a short time to really prove the setting. don’t run it wide open to warm it up but it should be at a fast idle. Nothing you do will be proven correct until the engine is warm.
Good Luck
Glad to be of assistance - please rate the solution because I will learn from your rating. Thank you

There are two idle screws one high, and one low. Your high adjustment idle screw needs to be adjusted.

SOURCE: Chainsaw won't start

Time to get out your trusty tool kit. Remove the side cover assembly and look at the recoil assembly. You should see a pair of fingers that when you pull the cord move toward the center. If the fingers are there and not broken, make sure they move when you pull the cord. clean them if dirty or have foreign objects (like sawdust) around them. If the fingers are broken, replace them. You should be able to purchase them from your local saw shop.

POULAN 42CC 18" PP4218 WHAT ARE THEY CORRECT


Make sure the fuel filter, air cleaner, and muffler are not plugged. Make sure the fuel lines are not decayed or other damage. Turn H and L jet screws CW to stops (lightly), then back CCW 1-1/2 turns each. This is a basic setting that should allow the engine to start and run. Allow the engine to warm up, then pull the throttle full on. Adjust the H jet screw CW until the engine starts to speed up. Correct adjustment is when the engine 4-strokes at speed unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L jet screw CW until the engine idles fairly well, but allows the engine to 'follow the throttle'. If you go too far, the engine will 'gasp' when throttled. Hope this helps!

Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Back the jet screws out only 1-1/2 turns each. Remove the carburetor cover and adjust T CW so that it contacts the throttle arm stop, then turn about 2 turns more. It may idle too fast, but don't worry about that for now. Once the two jet screws are preset, start the engine and let it warm up. Pull the throttle full on and adjust H jet CW until the engine starts to speed up. Correct final adjustment is for the engine to 4-stroke lightly unloaded, but immediately 2-stroke when cutting. Release the throttle (if the engine dies immediately, turn T CW until the engine will continue to run) and adjust L CW until the engine idles fairly well, but still allows the engine to 'follow the throttle'. If you go too far, the engine will 'gasp' when accelerated. T is set so that the engine continues to run, but the chain should not be trying to turn. Hope this helps!

Yes I have a echo CS-3450 type 1-E and have to work the throttle just to keep it running.changed the fuel filter,sparkplug,gas ratio 40:1


Check the fuel lines for decay or other damage. Make sure the muffler is not plugged. If the jet screws have slot heads, turn the H jet screw CCW somewhat until the engine 4-strokes at speed, but immediately 2-strokes when cutting. If the engine lags behind the throttle when accelerating, turn the L jet screw CCW about 1/8 to 1/4 turn. Hope this helps!

Inspect the jet screw (H and L) heads to see if the have slot heads or are 'D' heads which must be adjusted by a service dealer. Make sure to have fresh fuel mix with modern synthetic saw oil in the tank (50:1 ratio). Be sure to shake the container thoroughly each time just before adding fuel to the tank to prevent oil starvation. Inspect the fuel filter and air cleaner for plugging. Also, check the fuel line for decay or other problems. With slot-headed jet screws, turn both CW to stops (lightly), then turn each out CCW 1-1/2 turns. Start the engine and allow to warm up, then pull the throttle full on and turn H needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L CW so that the engine idles fairly well, but will still 'follow the throttle'. If the chain is trying to turn at idle, turn the idle speed adjustment screw CCW until the chain stops trying to move. Hope this helps!

I have a 452 echo. lost the manual in a move. the boys 8-9 decided to tune up the saw and now I can't get it running...can you help me with the begining setings..Thanks John


Likely, they have adjusted the H and L jet needles and maybe the idle speed screw. Turn both jet screws CW to stops (lightly), then back out each CCW 1-1/2 turns. This is a basic setting and should let the engine start and run. Start the engine and let warm up, then pull the throttle full on. Adjust H jet needle CW until the engine starts to speed up, but 4-stroking. Proper adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW for better idle, but allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but allows the engine to continue to run. Hope this helps!

How do you adjust high, low, and throttle on echo 3400 chainsaw


Ok, this is an easy job, and a quick tune up. First start up your saw, rev it some so it warms up. Next, make sure your saw idles, if not just turn up the idle a bit first before this. With your saw idling on the ground, turn the L screw about 1 turn either side of where it is, and listen to obtain the fastest and smoothest idle, that takes care of the L screw. Now the H screw must be adjusted while the the saw is at full throttle, turn the H screw and listen for maximum and smoothest engine speed. I sugest this be done with the chain and bar removed from the saw. After you adjust the L and H, then adjust idle to suit.

Starts, idles and runs but quits after a few seconds of cutting


Check the air cleaner and muffler for plugging. One screw adjusts the idle stop (idle speed) position and the H and L jet screws set fuel mixture for high speed and idle speed mixture respectively. Turn both jet screws CW to stops (lightly) then back each out CCW 1-1/2 turns. This is a basic setting and should allow the engine to start and run. Start the engine and allow to warm up. Pull the throttle full on and adjust H CW until the engine starts to speed up, but 4-strokes. Correct adjustment is when the engine 4--strokes running free, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW until the engine idles fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!
