Poor performance at hi revs on poulan 3314

fuel filter,air filter

Gently Tighten the carb adjustment screw fully tight then adjust it out 360 (full turn) then again a further 180 ( half a turn) and your idle speed should be set correctly. Let me know how you get on

Sadly, the 3816 is not designed for larger timber. 38cc is only for smaller limbs, As a general rule also the largest timber to cut should only be 2/3 of the length of the bar

sounds like you have a crank seal out of it, you ncan try to clean carb and check fuel lines etc, but usually when they rev high with out giving throttle means there is an air leak Good Luck 2StrokeJim

Generally this is a fuel / air ratio problem. Usually it can be solved by a carb adjustment. On the carb there are usually two screws, one marked low or L , the other marked high or H. Low is your adjustment for idle mixture, high is for mixture at full throttle. The saw should Always be adjusted to run well during the cut. Make adjustments a little at a time, then try The saw. Continue small adjustments untill the saw is performing well at full throttle while Cutting.

Maybe this will help.

First thing to check is the screen (spark arrestor) on the muffler if it has one. When these get clogged units often will idle fine, but not be able to rev up much or at all.

If the screen is clogged, clean it and reinstall it, should work fine then.

First, check the air filter and clean it well. Then make sure the spark plug is clean and gapped properly.

Then prime, start it up, and allow it to idle, even using the trigger to make it fast idle if you can. Using a small thin screwdiver, turn the high speed idle screw on the carb in small increments to the right, kepping the speed up on the trhrottle.

The idea is to screw it out until it sputters, then screw it a half turn back in. If it doesn't smooth out when turning it to the right, try going to the left.

Afterwards you may find it doesn't run at low throttle well. If not, try the same thing starting to turn left until it smooths out. If it doesn't, screw to the right. Again, the idea is to go until it sounds rough, then back off a half turn.

You should be able to adjust it to the point where you can open the throttle all the way with smooth sure throttle increase.

The low side of carb setting needs to be shut down. Will speed the idle up and stop from overloading on fuel. Only one catch. It takes a special tool to adjust. Go to poulanpro.com for your nearest dealer.

The carb low idle needs to be adjusted this is fairly common among the Poulan chain saws. Once you adjust the low idle from factory setting it will work
