Question about Poulan Pro Chain Saw 46cc 20"

1 Answer

Idle problems on poulan pro pp4620avl chainsaw. will start ususlly with full throttle, but can't seem to get a consistent low idle. Is there a tuning sequence for the H/L adjustments I need to know? Took it to a repair shop yesterday and they would not even look at it. they said I bought a cheap saw that will never run well. I am hoping there may be a better answer. Thanks Paul

I have several saws, among them a big Stihl and Husky, and a 46cc Poulan that I bought in 1994 that I have run through thee bars and a bunch of sprockets and chains. I use it today to buck my fire wood lengths. First, clean the carb out with a good spray carb cleaner. This will ruin your plug. Make sure your cleaner is okay. You really ought to replace all the plastic gas lines fron the carb and back and to the bulb. Make note of what goes where when you take them off.

When you get them, put the on, and some fresh oil/gas mixture. Pump that primer til you smell good gas, not the shellac smell of ruined gas.

If it starts, spray a little starter fluid in it and have your small screwdrivers on hand. Hold the throttle wide open, and ad just the hi speed screw til you hear it smooth out. Start by turning it to the right. If it doesn't smooth out or gets worse, start quarter turns to the left. Eventually you will get it to where it will winf to the max rpms.

Then, you have to work on the lo speed. I'd start by closing it and counting the turns. Try starting it bit by bit using 1/2 turns. Eventually you will get to a point where it starts easily at lo speed, and you'll find you may need to make a final adjustment on the hi speed. Mark down for the future how many turns each is.

Then go buy that guy's store and saw his door frame in half!

Idle adjustment


First start with the initial settings on both low and high side. They need to be 1 full turn out and the idle is set so that the throttle plate just starts to move.

FUEL MIXTURE SCREWS BEEN ADJUSTED IMPROPERLY. WHAT IS PROPER HIGH -LOW CARB SETTINGS FOR 40CC POULAN CHAIN SAW


Make sure the air cleaner is not plugged. Turn both jet screws CW to stops (lightly), then back each out 1-1/2 turns CCW. This is a basic setting and should allow the engine to start and run. When the engine is warmed up, pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Correct adjustment is when the engine 4-strokes running free, but immediately 2-strokes when cutting. Release the throttle and allow to idle. Turn the L jet needle CW until the engine idles fairly well, but the engine should 'follow the throttle'. It will tend to 'gasp' when pulling the throttle if you have gone too far. Idle speed screw should be set so that the chain doesn't try to turn, but the engine continues to idle. Hope this helps!

How do I adjust the carburetor on a Poulan 38cc chainsaw? Someone has messed with the low and high adjustment


Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Be sure to check the fuel filter, air cleaner, and muffler for plugging. Start the engine and allow to warm up--pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is reached when the engine 4-strokes at speed, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but will allow the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

Poulan stalls out


on the side of the carb you should find two screws, one for the low speed jet nd one for he high speed jet. Turning the low speed jet only about a 1/4 turn at a time, adjust it in or out until it idles smoothly. Go to arboristsite.com, chainsaw and do a search on tuning for more complete info.

How to adjust Zama carb on poulan pro


You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

Chain keeps turning while in the idle position . Poulan Pro 2075 chain saw.


There will be an idle (Low) speed adjustment screw somewhere on the saw (look in your manual). Adjusting this setting lower will prevent the chainsaw chain from turning in the idle throttle position. Basically you want to set it so the chain has just stopped moving... but you need to set this after the chainsaw has warmed up a little.
