Did you take carb apart at all?
Only the air filter to be able to get to fuel lines.
Saw is only two years old. Used it on Tuesday and it ran great. Would not start on Wednesday. That's when I discovered fuel line issue. Been working on it ever since. Have replaced fuel lines twice.
I will go hook up a spotlight and see what I can do.
Yellow and black wires are on the left and linkage is on the right of carb if I am remembering correctly.
Will I be working on the left or right side of carb if standing at handle end of saw?
You have to remove the carb.remove the two nuts and the t-25 head screw,squeeze throttle and hold the shaft (where cable connects to carb) and lift off filter cover and disconnect the cable-do not force or it will break the "z"bend off .Remove the primer line on left of carb and pull carb off of studs.Crimp thin fuel line with hemos and remove carb cover to clean and inspect.
Can't do any more tonight. Too dark to see and It's already a chore with my eyes. I will have to try in the morning. How will I respond back to you? This my first attempt at JustAnswer.
Are instructions available for disassembly of this carb?
One screw was on a plate on the bottom of carb. I removed it and found a little screen that was very grey.
What should I use to clean the screen?
Spray carb cleaner to clean out.The screen is grey.Was there any debris in it?
No real debris. Just a little thick grey dust like stuff. I cleaned it off easy with a Q-tip. Carb was really clean. I put it back on and tried it, same result. Will not even try to start. I will clean it again with carb cleaner in the morning.
I did notice it sounded as if it was sucking air when I released the primer bulb. I know it should when you push it in because it pushes air into tank but not when it releases. Am I correct? Is that where my problem is?
I know I will never ever own another POULAN!!!!
I tried a little gas earlier today and it would not start. That was before new plug and changing lines the second time.
Should I try switching lines back where the fuel supply goes to primer bulb and let it run with choke on? If it runs, would that mean I have a fuel inlet problem?
I'd leave fuel lines alone.Did you see a spark and check for scoring?
This morning: Checked for scoring, looked fine. While checking for spark, engine tried to fire. Connected plug wire and saw started without choke or priming. Ran for about 20 seconds. Restarted with choke and it ran ok (but fast) at half choke but when you engage trigger it bogs down and cuts off. Now what?
I have it running without doing any adjustments yet. It bogs a little at first, runs ok at half throttle but wants to bog down at full throttle.
Is the low speed screw the same as the one in the book refering to Idle Speed-T?
Is their a high speed adjustment? Where is it located?
Can you buy the special tool for making adjustments? I am already this deep in this project, I may as well buy more stuff.
Oh, by the way, I have not had to use primer bulb at all. Is this normal?
No,the idle speed is by itself and has a Phillips head.The adjustment screws are side by side and are splined requiring a special adjustment tool or modification.If you didn't need to use the primer the saw may have been flooded with excess fuel in the crankcase.I'm looking for the link for the tool .
I worked with the idle screw a little without much luck. Saw wants only to run on half choke. I can play with throttle and get it running at half speed but it will not run at full throttle, it boggs down and cuts off. Finally got it to idle after an hour. I guess I will have to wait until screwdriver arrives and see what I can do unless you have any other suggestions. I will contact you next week.
Open the high speed screw a hair if possible.
This saw is the biggest piece of SH** I have ever owned!!
It ran bad yesterday but at least it started. Today it will not start at all.
More new gas & oil (with a new can), another new plug & filter.
Cleaned carburetor again. Nothing works!
About ready to give up. My arm is about ready to fall off.
I will not touch it again until special screwdriver arrives.
Which screw should I open up first to get it to start?
Should I just give up and order new carburetor? I am kind of on a mission now to get it running. Too much time and money invested to quit.
When your tool arrives open both screws 2 full turns.I have had lots of trouble with the carbs also and have replaced many.I'll give you a part number and price just in case.
Got screwdriver. Opened up both screws ( to the left) one and a half turns and engine finally fired. Ran for about a minute with more smoke than normal and cut off. Will not start back. Now what????
Will try when I get back. Got to go out of town tomorrow.
That's what I'm here for.
It starts, it runs. Not as well as it should but I guess I will have to live with it. Only thing left to do is maybe replace carb. I will give it a while and see how it does. Thanks for all your help and patience. I will go back to your e-mail and accept answer.
