Doesn't stay running

Read owner book and lubricate. View safety first n dont rush

Faulty crankshaft oil seals.

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

The jet screws have a spline, there is a special tool to adjust these, part no. 530035560

Turn both jet screws CW to stops (lightly), then back both out 1-1/2 turns CCW each. This is a basic setting and the engine should start and run. Allow to warm up, then pull the throttle full on--the engine should 4-stroke. Adjust the H needle CW until the engine speeds up somewhat, but continues to 4-stroke. Correct 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 still allows the engine to 'follow-the-throttle'. Adjust idle speed so that the chain stops turning, but the engine continues to run. Hope this helps!

Hello,
a good starting point is the low speed screw at 1 3/4 turns and the high side at 1 1/2 turns. Hope it helps

no carb ajustment is done with a flat head screwdriver, first i would remove the card, disassemble it and blast it with compressed air because its probably just clogged up with varnish. to ajust the high low and idle screws bottom both out ( turn in all the way) then unscrew each one turn. from there start the saw and loosen in 1/4 turn at a time until it runs well

This does take a little time to get it just right. Start at one full turn for the h and l. Work on the high first and after you get the H running work on the Low. They have to work together. So if you get it to idle and run at full throttle but it hesitates when you pull the trigger just adjust the low a little higher.

The 3 adjustment screws are Idle, high and low.
First figure out which screws are which adjustment. Tighten the screws then turn them 1 full turn.
Then start the saw and get it warmed up. Work on the high adjustment. This does take a little while. after you get the saw running at high speed work on the low speed.

I would try Poulanpro.com and look at their user manuals for the adjustment. They are different on most saws. Hope this helps
