I was running this saw for about 2 hours at about a 30-50% duty cycle th-cam.com/users/postUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and it did a great job. I used the lever for the built in sharpener to clear chip buildup out more than to actually sharpen the chain. It managed to cut some hardwood stumps much larger than it's size without bothering the neighbors with hours of 2 stroke noise.
Thanks for the great vid. Someone gave me a saw and all the fuel lines were hard and broken off. Your vid shows where the lines go, all the other vids I saw lacked this important info. Thanks!
Super! I have been screwing around for some time trying to get the line into the tank. Never occurred to me to angle the cut line. Also the diagram was a help. I have a couple of these poulons around I volunteered to fix for freinds. You just saved me a lot of time. Thanks!
I watched three other tubes and became more confused. What they showed didn't match what I was seeing on my craftsman saw. Just by chance I watched your video and everything made perfect sense. I really appreciated your drawing of how the fuel flows. I had my saw back together in 30 minutes (I work slowly) and it runs perfectly. Thank you!!!
Thanks pal. After being given a pro saw that was 5 years old and used once all of the fuel line was mush. All 6 to 8 youtubers, I was somewhat confused by proper hookup. Even one of the kits order only had 1 size line , then really confused things. Your video is definitely the only one that needs to be on TH-cam for this issue.
Congrats on getting it right. So many INCORRECT You Tube vids on this. The filter goes on the small diameter line on the hole closest to the filler cap. The return line (larger) dia. Hose goes to the farthest hole from fuel filler cap. The lines to carb depend on the model so right and left won’t help. The diameter of the fittings on the carb will! Match them and you are golden. Nice touch with the diagram.
I watched all of the other confusing videos and yours is by far easier to understand. I have had lines in reverse order and couldn't understand why I wasn't getting fuel to the carb. Your diagram was a big help. Thanks for taking the time to straighten this mess out.
Thanks for clarifying the smaller line and larger line routing, the purpose of the plastic nipple and which line it goes on. Also my bulb is the screw mount type and if you take it off, the back side actually has the two connections labeled; tank and carb. Very helpful. This is the video to watch of all the videos on TH-cam trying to explain the correct fuel line replacement.
Big thumbs up! My fuel lines were rotten and fell off when I tried to replace my primer, and I couldn't tell where they had been connected. I searched for a fuel line diagram for hours before finding this.
Hate to tell ya since this is still the best video for this particular chainsaw, the LARGE line goes from filter to carb SMALL line is for both ends of purge bulb. If you do it the other way around you WILL have leaks. The tank grommet for supply line is way to big for the small line. And...if you use large line for purge, the inner tank fitting will not go through the wall of the tank which is how it seals.
Mine fits snugly. I contacted Poulan with this question as I investigated this source of confusion. They informed me the fuel line is smaller diameter because fuel is drawn with vacuum. The return line is larger diameter because it's function relies on gravity. Thank you very much for commenting! In the end it doesn't make a ton of difference. I've talked to repair guys that say hog out both of the holes and use even larger diameter in both then adjust the carb.
@@MonacoGP_On_TH-cam There may also be minor differences in model years. Mine is a 2013 PP2050AV. The small fuel line is loose as a goose in the tank grommet. It came factory with a fuel line I have never seen anywhere else. It was 2 lines in one, a small line inside the large line. Ever seen that? Anyhoo, the large diameter made it fit the grommet but the fuel filter was of course connected to the inner line. (if that makes sense)
thanks...my lines were so degraded that I couldn't tell where they orginally went and it was driving me nuts, trying figure out what the opening was on the far right side of the compartment. glad I found this video
I am currently working on a 16inch Craftsman that looks identical to the Poulan you're working on. It is clear to me that it has never been opened up. The lines have never been changed. The carb is different as both of the copper tubes are on the right side of the carb. The lines are routed differently. The line that goes to the filter is the larger line and it goes through the hole below the right side of the carb. The small coupler is in this line and the fuel filter, with a short piece of tubing, is attached to it. That line then goes to the primer. The line on the other side of the primer goes to the bottom copper tube on the carb. The small line is the drain line that attaches to the top copper tube on the carb and goes through the small hole below the left side of the carb. So, even though the saws look identical there are differences. I did find a video with my identical saw and the tubing was routed as I described.
Very nice video everything tide and in order ,the diagram was helpful simple easy to understand how the circulation mast be done , thanks for your help
I replaced my fuel line set yesterday and found it imposable to get the fuel filter on the smaller line, so I had no other choice but to use the larger line. I tried everything, stretching it, heating it, but no way was it happening. I'll be going out today to get the 2 -stroke oil so I'll find out then how it runs and if it made any difference. *Maybe you could do a video on how you got the fuel filter on the smaller line.
It's like threading a needle. Somehow i just force it on. I just had to replace again last week five or so years since I made this video because I'm always leaving gas in mine.
Just wanted to offer an alternative to using forceps, as I did not have these. Cut the tubing as was instructed in the video, and then thread some 30# test fishing line through the tubing at the center of the thickest part of the cut. Feed the fishing line in first, followed by the tubing. Using bar oil to lube helped, also.
I have a POULAN SUPPER CLEAN does not tell me the model less that is it. 0D of gas line is 1/8 goes tank to the carb no primer ball . Can I add on a ball primer to it? Smaller line that kit would that tell me the OD ?
I only prime 2 or 3 times MAX!! Pull until you get the slightest sign of life from the motor almost starting. Very Important! NOW Push in the choke! (NOT one more pull after it showed signs of almost starting) Now it should start with a few more pulls. 2 to 3 usual. I do this with all my 2 cycle equipment, no matter the manufacturer. Has never failed me.
Got a Poulan 18 PR 4218. it appears that the bar is a little bent so we bought a new bar installed with a new chain and still looks crooked. How do I straighten this thing up?
Any idea where to get the valve item you describe on the return to the tank? Mine lines are old and falling apart. I tore it apart but don't see the valve.
Is the small nipple a one way valve? or can i just throw it out(mine is crumbling) and feed a line snugly into the tank hole? edit: if you included the FILTER in you diagram,it would be perfect, i have the SAME diameter lines and holes on the saw, guess the thin one was drilled out.
Question: First off, let me say THANK YOU SO MUCH for taking the time to video this. Ok, here's the question: I have a Poulan Pro 3516AVX. Using the smaller diameter line on the suction from the tank to the carb. Since the line is smaller, wouldn't that restrict the gas to the carb when the gas demand is at its highest? Just wondering. Please help. Tommy.
Loved this video. I saw videos on how to adjust the High and Low settings, but no one comments about what the "T" screw adjusts, or how to adjust it. What is the "T" screw?
This is a great video, thanks for your time in making an awesome video. To the “NUTS” who gave this video a “THUMBS DOWN” you must have one screwed up brain. Also, just last night I was working on mine and it got late, so I stopped to think over the situation... found this video and everything he has pointed out makes perfect sense.👌 My job will be so much easier today.
Thank you for watching and for the kind words. The whole thumbs down thing on videos of this type boggles the mind. It's not like I'm making any controversial statements. Just trying to help people out for no monetary gain. Good luck with your repairs!
Hey, good video. Just a couple of comments to help make things easier and a question at the end.. first, when preparing the lines for inserting into the tank. if you use the skissors to cut up from the squared end of the tube it is easier to get the angled cut to allow for insertion into the hole. Next, insert the line from underneath (inside the tank). It is easier to pull through. In the video you do not mention how difficult it is to get the fuel filter connected to the small line. (It took me hours!!) Which led me to my question. Why would the smaller line be on the fuel supply side? Does it not restrict the fuel flow? Bulb side is only used to prime the system then no longer required so does not need to be large?
Ken Bowes Thank you for watching and for the input and comment. To answer your question; The smaller diameter fuel pick-up line has vacuum to pull the fuel through whereas the return line is basically gravity and therefor needs to be larger and less restrictive. At least that's the explanation I came across in researching this repair.
Monaco GP New fresh gas, so not that. New spark plug set at 15 - 20 thou... It stalls out before I can get to the throttle.. Arm is getting tired today. Will try again tomorrow. Thanks for your replies.
I have same saw. Have some work to do on it. How do you tell if primer bulb is bad? or how do you know it fuel filter is bad? or if it needs a carb or spark plug adjustment?
If the primer bulb is bad it wont feed fuel. Usually on the second or third prime you feel a difference in the pressure required, it gets more firm, to push the bulb because the air is largely out of the lines etc. You could test it by removing it and running fuel through it in a cup. However, you should be able to smell fuel if you've been priming and trying to start. If you're getting fuel then the issue is spark. Check the plug. Is it wet with fuel? Is it coated in oil? If its been a couple years replace it. They're only $3. Of HUGE importance is to make sure you're using fresh fuel. My other yard tools by Stihl seem to be unbothered by stale gas. Not so this or any other chainsaw.
the fuel lines looked good on this chainsaw why replace them if it bogging down all you needed to do was adjust the carb from the idle screw to lean to high to adjust it some times when you run a small engine it vibrates the screw off the factory adjustment and it also dependents the factory adjustment may not be set for your elevation the higher in elevation above sea leave you will have to adjust any carb most carbs are set to lower sea level just saying but good tutorial on how to replace them and you should only replace them if there comply rotted may be they were i don't know but great video any ways
I had lent the saw to a friend. The lines were rotted. They tried to repair but ran the lines incorrectly. Hence the reason for the video once I figured out the correct configuration. So in fact I did the video with the new lines already installed. Thank you for watching!!
Wasn't trying 2 say you were wrong I guess I didn't explain myself right all I was trying to get out of this video was which fuel line goes to the high side of the tank and which fuel line goes to the low side of the tank I I'm a visual person I think your video would have been much better if we could have seen exactly where each fuel line came from and where it ended up at. It was a very good video. I just thought it could have had a better visual on the saw its self that's all I was saying. Not everyone it's good at following drawings. I was Not trying to talk down about your video. I was tring to get you to see it from my point of view.
I think your question is the same as mine, Dennis. Which hole in the tank is for the fuel pickup line and which is for the return? Perhaps the two holes are different sizes, which would be an indication-the smaller for supply and the larger for return. I believe that someone answered this question in the comments-at least for the Poulan pro-that the pickup line with fuel filter penetrates the hole that is closest to the tank fill cap and the return line goes through the hole furthest from fill cap. Amaright?
I do have a related question. I have the Poulan 5020 and when my saw is hot it doesn't seem to prime. Is that because it's hot and evaporating the fuel as some have suggested?
Yes. Once hot you shouldn't need to prime. Chainsaws are more sensitive to spark plug, carburetor and fuel mixture than other small engines. For instance, if my fuel is 2 months old mine doesn't want to restart yet everything else will run on last year's.
I use some really thick generic stuff in a green bottle from Walmart. That's made it a little better. But yes it does go through a lot of bar oil and leaks out all over the place if you leave any in the reservoir. It's a decent saw but underpowered for the 20" bar. It's not a light saw either. I thought I was making a smart choice because the design was similar to the two model year old parent company, Husky, model. I probably should have bought a Stihl.
@MonacoGP- Ok thanks, will look into it. Is it bar and chain oil or standard motor oil and what weight is it? As a side note, I have found that opening the spark plug gap to about .030 helps quite a bit with stalling issues. It comes from the factory preset to almost nothing and when the motor is warmed up that can cause it to bog down and stall. Simple solution. Also there are a few vids on how to modify the carb on this model to increase HP. I haven’t attempted it yet but it looks interesting. Thanks for the reply.
I am trying to figure this out and I am not "mechanically" inclined. But I think maybe I have it now, although it I would have more helpful had you actually been doing all the work of actually installing the fuel line vs. this goes here and that goes there; I am a visual learner. I'm not at all intuitive when it comes to this kind of work (lol). Also I think it would have been more helpful if your drawing were in orientation to chainsaw, i.e. drawing with tank on the bottom and carburetor on top. That being said this was helpful and I'll give it a go as soon as I can locate a supplier for the fuel line. Thank you
My saw worked great after I got new lines put in with a new carb. It then would stall when cutting. I had to hold the throttle just right to cut with the right speed. A month later and I am trying to use it. It starts and idles great. However, as soon ask I squeeze the throttle it stalls. What could that be? When the throttle plate opens, it stalls. Ii have the Poulan wild thing. I had a hard time getting the fatter tube through the hole in the tank.
@@MonacoGP_On_TH-cam Thanks. I didn't adjust it yet. I sprayed carb cleaner in it and tried again. Works well but as soon as I squeeze the throttle far enough to open the butterfly is when it stalls. The main linkage hits the next throttle linkage. It runs fast enough to cut through the limbs. I guess its worth the shot at adjusting it. Is there a video for that?
If you Wanted to exand the audiance for this video you should specify the model and series of the Walbro carburator that is in the saw. Put it in the title of the video and you'll get views from people troubleshooting dozens of different devices that have 2 cycle engines, not just an MTD made chainsaw.
Thank you for the advice. I can't access it now because I'm in a mobile platform but I do have 35 or 45 models and manufacturers listed in the kewords list.
There's only two diameters and if you buy the kit part number I show in the video it comes with both as well as the plastic nipple that goes on the end of the return line inside the tank to prevent it getting pulled out.
The smaller tube is the fuel pickup tube. The larger diameter is the exit to then through the primer bulb then back to the tank. If you have the same saw, as you're looking at the carb from the back, the pickup/inlet is on the right side and the exit is on the left.
Since you like things so correct, please allow me to help you with the pronunciation of Poulan. I live in a city in Louisiana where these saws (and other Poulan products) were made for many, many years. Poulan is pronounced pŌle' ŭn. Long "O" sound and accent for first syllable. Second syllable is almost an afterthought sound. Have a nice day!! :)
It's counter intuitive. The smaller diameter hose is the fuel line. The larger hose is the return. It has to due with having unrestricted gravity flow back to the tank whereas the carburetor actively vaccum pulls fuel from the tank.
nice saw , they were on sale last year at tsc for 100.00 , i got 3 or them , one had bad seals from day one , 10.00 dollar fix , i sold 2 of the for 150.00 each so my saw cost me 10.00 ,, lol
LOL good job. They're fine for moderate to even heavy home use but if you're making a living at it not so much. I had hoped they would be a little more robust in the build because it was supposed to be two generation prior Husqvarna. While it may be based on that they certainly cheapened the build. Thank you for watching!
Would think the larger size hose would be the feed side with the filter going to the carburetor. The smaller size would be the return side back to the tank.
@robertboyd1513 That would be the logic but apparently on the feed side there's suction and therefore the smaller diameter is indicated. The return side is a drain so the larger diameter flows better.
I need to go to menards some time and buy some new tools then if they don't have them I'll look on Amazon But I use my battery drill for taking apart those and weed eaters because its faster for me but then I need longer tools to reach the screw heads so I'm pumped without those tools the ones i do have are broken Faster is better for me cause i use the daylight
Failed to mention which Way fuel flows through the carburetor you can only go one way I hope I've helped you got it on backwards it's not going to work you got to tell people which nipple on the carburetor is the inlet and which is the outlet
I do mention which way the fuel flows and even draw a diagram in the video. It's not running the wrong way. The feed side tubing is smaller diameter than the return, the bulb pulls not pushes fuel through the carb and the plastic nipple goes on the end of the return line inside the tank to prevent it from pulling out. Thank you for the input though. Try watching the whole video.
I wasn't saying you got it wrong. Just saying I had a hard time with this kind of issue until Steve's small engine saloon broke it down for me. The primer pulls fuel through the carb not pushing it through.
@@dennismorris3220 I just said that about the fuel direction. That it pulls fuel through not pushes it. It's in the diagram I draw in the video. I'm trying to see why you've commented when all you're saying is exactly what I said in the video and in my replies to you.
The filter goes on the end of the thinner line that goes to the input side if the carburetor. Make sure that line is long enough inside the tank to allow it to flip around to always be at the "bottom" of the tank even when you have the saw on its side. The larger diameter line is the return to the tank from the outlet side of the carburetor and gets that little plastic nipple on the end of it inside the tank to prevent it from pulling through.

No. The feed line has suction provided by the operation of the engine. The return line is larger because it's gravity feed.

Loved this video. I saw videos on how to adjust the High and Low settings, but no one comments about what the "T" screw adjusts, or how to adjust it. What is the "T" screw?
It's the Idle speed screw
Where do the purge lines connect to.
This is a great video, thanks for your time in making an awesome video. To the “NUTS” who gave this video a “THUMBS DOWN” you must have one screwed up brain. Also, just last night I was working on mine and it got late, so I stopped to think over the situation... found this video and everything he has pointed out makes perfect sense.👌 My job will be so much easier today.
Thank you for watching and for the kind words. The whole thumbs down thing on videos of this type boggles the mind. It's not like I'm making any controversial statements. Just trying to help people out for no monetary gain. Good luck with your repairs!
Thank you so much awesome video gave it a thumbs up help me out a lot
You're welcome. I'm glad it helped and thank you for the thumps up!
Not as clear as you wanted but the diagram helped, missed the weighted fuel pickup but we got it for the most part.
Thanks for your help
You're welcome. Thank you for commenting.
Hey, good video. Just a couple of comments to help make things easier and a question at the end.. first, when preparing the lines for inserting into the tank. if you use the skissors to cut up from the squared end of the tube it is easier to get the angled cut to allow for insertion into the hole. Next, insert the line from underneath (inside the tank). It is easier to pull through. In the video you do not mention how difficult it is to get the fuel filter connected to the small line. (It took me hours!!)
Which led me to my question. Why would the smaller line be on the fuel supply side? Does it not restrict the fuel flow? Bulb side is only used to prime the system then no longer required so does not need to be large?
Ken Bowes Thank you for watching and for the input and comment. To answer your question; The smaller diameter fuel pick-up line has vacuum to pull the fuel through whereas the return line is basically gravity and therefor needs to be larger and less restrictive. At least that's the explanation I came across in researching this repair.
Monaco GP Thanks for that info. I got everything back together, new fuel, and it will fire but won't run more than a second or two. Any ideas??
Ken Bowes spark plug or bad gas. Does it stay running if you get to the throttle quickly enough?
Monaco GP New fresh gas, so not that. New spark plug set at 15 - 20 thou... It stalls out before I can get to the throttle.. Arm is getting tired today. Will try again tomorrow.
Thanks for your replies.
@Fredrick Kincaid Fredrick, no, not yet. I will let everyone know the resolution when it happens.
I have same saw. Have some work to do on it. How do you tell if primer bulb is bad? or how do you know it fuel filter is bad? or if it needs a carb or spark plug adjustment?
If the primer bulb is bad it wont feed fuel. Usually on the second or third prime you feel a difference in the pressure required, it gets more firm, to push the bulb because the air is largely out of the lines etc. You could test it by removing it and running fuel through it in a cup. However, you should be able to smell fuel if you've been priming and trying to start. If you're getting fuel then the issue is spark. Check the plug. Is it wet with fuel? Is it coated in oil? If its been a couple years replace it. They're only $3. Of HUGE importance is to make sure you're using fresh fuel. My other yard tools by Stihl seem to be unbothered by stale gas. Not so this or any other chainsaw.
Very helpful. Thanks for this. Agree with comment by CajunWon. If you redo video, you might consider starting with the diagram.
Thank you for the feedback and for watching
The fuel line kit you showed does not fit snuggly in my poulan pro tank. It is to small and lets air escape.
the fuel lines looked good on this chainsaw why replace them if it bogging down all you needed to do was adjust the carb from the idle screw to lean to high to adjust it some times when you run a small engine it vibrates the screw off the factory adjustment and it also dependents the factory adjustment may not be set for your elevation the higher in elevation above sea leave you will have to adjust any carb most carbs are set to lower sea level just saying but good tutorial on how to replace them and you should only replace them if there comply rotted may be they were i don't know but great video any ways
I had lent the saw to a friend. The lines were rotted. They tried to repair but ran the lines incorrectly. Hence the reason for the video once I figured out the correct configuration. So in fact I did the video with the new lines already installed. Thank you for watching!!
Wasn't trying 2 say you were wrong I guess I didn't explain myself right all I was trying to get out of this video was which fuel line goes to the high side of the tank and which fuel line goes to the low side of the tank I I'm a visual person I think your video would have been much better if we could have seen exactly where each fuel line came from and where it ended up at. It was a very good video. I just thought it could have had a better visual on the saw its self that's all I was saying. Not everyone it's good at following drawings. I was Not trying to talk down about your video. I was tring to get you to see it from my point of view.
I miss spoke. You clearly explain which way the fuel flows.
I think your question is the same as mine, Dennis. Which hole in the tank is for the fuel pickup line and which is for the return? Perhaps the two holes are different sizes, which would be an indication-the smaller for supply and the larger for return. I believe that someone answered this question in the comments-at least for the Poulan pro-that the pickup line with fuel filter penetrates the hole that is closest to the tank fill cap and the return line goes through the hole furthest from fill cap. Amaright?
I do have a related question. I have the Poulan 5020 and when my saw is hot it doesn't seem to prime. Is that because it's hot and evaporating the fuel as some have suggested?
Yes. Once hot you shouldn't need to prime. Chainsaws are more sensitive to spark plug, carburetor and fuel mixture than other small engines. For instance, if my fuel is 2 months old mine doesn't want to restart yet everything else will run on last year's.
@@MonacoGP_On_TH-cam Thank you sir. You've been a great help. Keep up the great videos.
Great video! I have the same model, did you come up with any solutions to the extreme amount of bar oil that flows?? Mine flows like the Exxon Valdez.
I use some really thick generic stuff in a green bottle from Walmart. That's made it a little better. But yes it does go through a lot of bar oil and leaks out all over the place if you leave any in the reservoir. It's a decent saw but underpowered for the 20" bar. It's not a light saw either. I thought I was making a smart choice because the design was similar to the two model year old parent company, Husky, model. I probably should have bought a Stihl.
@MonacoGP- Ok thanks, will look into it. Is it bar and chain oil or standard motor oil and what weight is it? As a side note, I have found that opening the spark plug gap to about .030 helps quite a bit with stalling issues. It comes from the factory preset to almost nothing and when the motor is warmed up that can cause it to bog down and stall. Simple solution. Also there are a few vids on how to modify the carb on this model to increase HP. I haven’t attempted it yet but it looks interesting. Thanks for the reply.
What makes the saw get stuck on hi
Great video, thanks for sharing.
You're welcome
Should have done the complete process still don't know how to run the line's?
Thanks. I'm about to do this
I am trying to figure this out and I am not "mechanically" inclined. But I think maybe I have it now, although it I would have more helpful had you actually been doing all the work of actually installing the fuel line vs. this goes here and that goes there; I am a visual learner. I'm not at all intuitive when it comes to this kind of work (lol). Also I think it would have been more helpful if your drawing were in orientation to chainsaw, i.e. drawing with tank on the bottom and carburetor on top. That being said this was helpful and I'll give it a go as soon as I can locate a supplier for the fuel line. Thank you
Feel free to make your own video for no compensation
The hand drawn diagram was the key.
Thank you for watching and commenting.
Lots of good information.
Thank you for the feedback. I hope it helped.
My saw worked great after I got new lines put in with a new carb. It then would stall when cutting. I had to hold the throttle just right to cut with the right speed. A month later and I am trying to use it. It starts and idles great. However, as soon ask I squeeze the throttle it stalls. What could that be? When the throttle plate opens, it stalls. Ii have the Poulan wild thing. I had a hard time getting the fatter tube through the hole in the tank.
Sounds like either the carb needs adjusting or the gas may be old. I've noticed these saws are very temperamental in anything but new gas
@@MonacoGP_On_TH-cam Thanks. I didn't adjust it yet. I sprayed carb cleaner in it and tried again. Works well but as soon as I squeeze the throttle far enough to open the butterfly is when it stalls. The main linkage hits the next throttle linkage. It runs fast enough to cut through the limbs. I guess its worth the shot at adjusting it. Is there a video for that?
There are videos out there for adjusting the carb. I haven't done one yet. It's on my list of to do's because mine needs some tweaking at idle.
If you
Wanted to exand the audiance for this video you should specify the model and series of the Walbro carburator that is in the saw. Put it in the title of the video and you'll get views from people troubleshooting dozens of different devices that have 2 cycle engines, not just an MTD made chainsaw.
Thank you for the advice. I can't access it now because I'm in a mobile platform but I do have 35 or 45 models and manufacturers listed in the kewords list.
Can you tell me what the three size of gas lines are
There's only two diameters and if you buy the kit part number I show in the video it comes with both as well as the plastic nipple that goes on the end of the return line inside the tank to prevent it getting pulled out.
how do you know which tube on the carb takes the fuel input and which takes the primer bulb tube?
The smaller tube is the fuel pickup tube. The larger diameter is the exit to then through the primer bulb then back to the tank. If you have the same saw, as you're looking at the carb from the back, the pickup/inlet is on the right side and the exit is on the left.
@@MonacoGP_On_TH-cam Thank you. This is what I needed. From the bulb to the opposite side of the carb.
@@jayztoob glad to help
Well, that didn't work.
how much do you think some one will charge??
Since you like things so correct, please allow me to help you with the pronunciation of Poulan. I live in a city in Louisiana where these saws (and other Poulan products) were made for many, many years. Poulan is pronounced pŌle' ŭn.
Long "O" sound and accent for first syllable.
Second syllable is almost an afterthought sound.
Have a nice day!! :)
Thank you
Glad it helped. Thank you for commenting!
Thanks!
My question is which is the inlet and which is the outlet on the carburetor
It's counter intuitive. The smaller diameter hose is the fuel line. The larger hose is the return. It has to due with having unrestricted gravity flow back to the tank whereas the carburetor actively vaccum pulls fuel from the tank.
nice saw , they were on sale last year at tsc for 100.00 , i got 3 or them , one had bad seals from day one , 10.00 dollar fix , i sold 2 of the for 150.00 each so my saw cost me 10.00 ,, lol
LOL good job. They're fine for moderate to even heavy home use but if you're making a living at it not so much. I had hoped they would be a little more robust in the build because it was supposed to be two generation prior Husqvarna. While it may be based on that they certainly cheapened the build. Thank you for watching!
I done it to lol thanks for explaining
Would think the larger size hose would be the feed side with the filter going to the carburetor. The smaller size would be the return side back to the tank.
@robertboyd1513 That would be the logic but apparently on the feed side there's suction and therefore the smaller diameter is indicated. The return side is a drain so the larger diameter flows better.
@@MonacoGP_On_TH-camDoes the return line fitting pull back into the top of the tank or is it just loose near the top?
Does the nylon fitting snap into the top of the fuel tank or push into the top or is is just loose?
@robertboyd1513 That little fitting stays inside the tank. I pulled the line out of the tank until it was taught against the top of the tank.
@@MonacoGP_On_TH-camOn mine one end of the fitting was lodged into the hole in the top of the tank with the hose attached to it. Strange
Thanks bro!
You're welcome!
This was the best
Thank you!
how many times did you use the saw before you had to fix it
Not many. I lent it out and in the fall and the person I lent it to left has in it all winter. By spring the lines had rotted.
Much easier if you take the carb off. Damned!
It was no problem for me to leave it on.
very well done ,
Thank you!
I need to go to menards some time and buy some new tools then if they don't have them I'll look on Amazon
But I use my battery drill for taking apart those and weed eaters because its faster for me but then I need longer tools to reach the screw heads so I'm pumped without those tools the ones i do have are broken
Faster is better for me cause i use the daylight
Good info.
Oh and thanks for the video!
Great video life saver
what about one with impulse line?
Appreciate the video! 👌🏽👏🏼
You're welcome. Thank you for watching.
Failed to mention which Way fuel flows through the carburetor you can only go one way I hope I've helped you got it on backwards it's not going to work you got to tell people which nipple on the carburetor is the inlet and which is the outlet
I do mention which way the fuel flows and even draw a diagram in the video. It's not running the wrong way. The feed side tubing is smaller diameter than the return, the bulb pulls not pushes fuel through the carb and the plastic nipple goes on the end of the return line inside the tank to prevent it from pulling out. Thank you for the input though. Try watching the whole video.
I wasn't saying you got it wrong. Just saying I had a hard time with this kind of issue until Steve's small engine saloon broke it down for me. The primer pulls fuel through the carb not pushing it through.
@@dennismorris3220 I just said that about the fuel direction. That it pulls fuel through not pushes it. It's in the diagram I draw in the video. I'm trying to see why you've commented when all you're saying is exactly what I said in the video and in my replies to you.
and how do i know that, that is exactly my problem now; i am already assuming the bulb PULLS fuel thrun the carb, thanks to the video.
@@josepeixoto3384 thank you for commenting!!!
Hey where is the filter in the gas thanks goes
The filter goes on the end of the thinner line that goes to the input side if the carburetor. Make sure that line is long enough inside the tank to allow it to flip around to always be at the "bottom" of the tank even when you have the saw on its side. The larger diameter line is the return to the tank from the outlet side of the carburetor and gets that little plastic nipple on the end of it inside the tank to prevent it from pulling through.
