The engine is running hot. A build up of chain lube/saw dust/dirt is likely blocking cooling air to the cylinder cooling fins (and gas line and carb) causing the fuel to boil (vapor lock)
Compressed air, played around openings in the shroud, will sometimes remove enough of the obstruction to help and is worth a try. Best solution is to split and remove the case/cover, after which, the engine and shroud can be throughly cleaned. Be sure to stuff a clean rag in the carburater throat to keep debris out.

I HAVE A NEWER POULAN PRO CHAINSAW.STARTS AND RUNS FINE FOR 10-15 min. THEN DIES AND WON'T RESTART UNTILL COLD. THEN IT REPEATS THE SAME PROBLEM.


If it pulls easier than it used to when you try to start, you have low compression. Once the saw warms up, it doesn't have enough compression to run. If that's the case, there is no easy fix, it needs piston rings.

Carb ajustment


Only Info I see is "Homelite Chain Saws" - not much to go on.
Most saws have two carb adjustment screws, Hi, and Lo.
Assuming the saw will start and run enough to warm up, then
adjust the Lo screw in, clockwise, until the motor starts to slow down,
turn only about 1/8 turn at a time. From the point where it starts to slow down, turn it out about 1/4 turn. This should give you a decent idle. Now pull the throttle, and see what happens.
A - Saw runs up to speed, but dies off, or starts to slow on it's own.
turn Hi idle screw out about 1/4 turn.
B - Saw speeds up, but runs sluggish, fat - not real hi end.
Turn Hi screw IN, about 1/8 or so, and try again, or adjust
while running at full throttle. (best way)
IF it won't run well, try turning both screws all the way in to seat them, then come back out about 1-1/2 to 2 turns. this should get you in the ballpark to set things up as above.

Once the saw is running well, adjust the idle screw to a smooth idle but slow enough that the chain stops moving.

Stay safe

Homelite d2850b chainsaw air-fuel adjustments. white adjustment on left red adjustment on right. how do i calibrate?. Alsoit just seems as though its getting too much gas. Tried to warm it up a bitt with a...


If the fuel tank was completely full, I would expect fuel leakage from the tank vent--don't make a practice of overfilling. Give it a little breathing room for expansion. Check the air cleaner and muffler for plugging. White and red adjustments mean nothing to a color blind person. There should be an 'H' and 'L' cast into the plastic surface or on the carburetor body itself near the adjustments. Turn both screws CW to stops (lightly) and then back out each 1-1/2 turns CCW. 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 still 4-stroking. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Release the throttle and adjust L CW until the engine runs fairly well, but allows the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Homelite chainsaw won't stay running


Make sure you are using fresh fuel mix (50:1 ratio). Don't use boat motor oil in a saw--only modern synthetics made for saws. Always premix the oil and fuel thoroughly before adding to the saw. Check the fuel filter for plugging and the condition of all fuel lines, plus the primer bulb condition. Check all carburetor fasteners for tightness. Make sure the air filter and muffler are not plugged. If still no help, you may need to service the carburetor. For an excellent article on Walbro carburetors, go to: http://www.drystacked.com Pay particular attention to the placement of the lower diaphragm and the cover gasket--interchanging positions of them cause many headaches. Adjustment of the two jet screws require a special 'D' screwdriver which may necessitate a trip to a servicing dealer for adjustment. Hope this helps!

Carburator adjustment for Homelite xl 12 chain saw


Turn both screws CW to stops (lightly), then back out each CCW 1-1/2 turns. This should get the engine running if it will. If it does not, check the lower diaphragm on the carburetor for hardness or cracking. You appear to be running on prime only--the carburetor doesn't seem to be pumping in fresh fuel. You may need to do a carburetor clean and re-kit. Check the fuel line condition and the fuel filter in the tank for plugging. Make sure the muffler and air cleaner are not plugged. Once you get the engine to continue running, warm the engine up. Open the throttle and adjust the H needle CW--the engine should start to speed up, but still 4-stroking. The proper setting is 4-stroking, but immediately 2-stroke when cutting. Release the throttle and adjust L needle CW so that the engine runs fairly smoothly, yet will allow the engine to 'follow the throttle'. Set idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

THE ENGINE RUNS FINE FOR 10 SECONDS THEN KIND OF DIES OUT BUT WILL THEN RUN FINE FOR 10 SECONDS AND THEN DIE OUT


Try replacing the in-line fuel filter, the Air Filter and Spark Plugs. Also make sure that you are using the proper start up procedure. In many cases that means using the highest choke setting until the engine tries to start, then going to the next choke setting and so forth until you get to no choke. It is imperative that you let engine run for at least 5 minutes before use to warm up. This will ensure a longer life and consistent running.

Runs well untill it gets hot. then cuts out


If it's the little xl model, it's probably the ignition coil breaking down when it gets hot and therefore it can't and won't be able to handle a load. Also, scarred pistons skirt or rings could also be some of the problem here. Make sure your mix for a Homelite saw is 40:1 not 50:1 like most saws are. Homelite seems to run better with a heavier oil mixture. Good luck.

HOMELITE Textron Chain Saw, wont stay running properly.


The preset is to turn them all the way in (Don't tighten them hard or you will damage the needle) and then back each out 1 1/2 turns. This will get you started. You can then run it at full throttle and turn the high speed jet in untill you hear a change in the RPM. Then turn it out untill you hear the same. Find the happy medium.
