I got this exact chainsaw and a bunch of files,greases and wrenches for $30 in an auction. I find these chainsaws have a lot of complaints on hard starts and bad running. After I got myself comfortable with the parts (courtesy of your videos) these chainsaws are fine once you tune them really well. Thanks for the handy videos!

Good to see that you try not to let anything beat you. Thanks HG

Thanks for the great tutorials... feeling like I am deep in the saw woe weeds right now. But great to see some well laid out camera and voiceover work. And I am envious how easy you are making the tubing onto fittings work!

Fixing things allways came very easy to me. It's strange to me that some people cant do these types of things but everyone is good at something I guess. KZfaq was a God send to a DIY guy like me. Crazy to think someone messed that saw up that bad then threw it away. They will say "Poulan is junk" when it was their fault it was broke. Good repair video!

All I can say is welcome to the club. The one I HAD was just like this, new carb and all. I could never get it to open up. When the secondary would start, it'd lean out and die. I bent linkag4es and did everything I could think of except getting out the BIG hammer or cranking the wood splitter. All I can say now is 'Thank God and Greyhound you're GONE' as Roy Clark's song goes. Blessings!

Just getting into tinkering with small engines and things. I found one of these on marketplace for $10 this video was very informative and taught me a lot I didn’t know. Can’t wait to get mine apart and see what I find. Thanks for the great tutorial and tips.

Hello Inside House Garage, I have my first small engine project coming up with my grandpa's old Ryobi 31cc weed eater , this idea of mine came from you because I've always been interested in it since I was younger then I started watching your vids about a month ago and I love how you always explain what you are doing and are very confident about getting every project you do running good. And that brought me the courage to start working on small engines. I hope you can read this and give me some tips on my first small engine project. Thank you

You are 100% on the mark. That is Amazon/eBay Chinese after market carb for Poulan. They do work well but you have to do some modifications to make it work on Poulan 42cc saw. I ended up shortening the throttle linkage on carb with pliers to prevent rubbing on rubber closing as it was causing throttle to be stuck.

I have the exact same saw. It's sometimes hard to start but once it starts it runs great. I can tell that looks like an aftermarket carburetor. The original carburetor has a plastic piece that opens the secondary throttle

Well you can tell the person that gave it away or even the person that tried to fix it didn't watch your channel or your videos. All they had to do was watch your channel. Great video and fix!! Can't wait for the next one on this saw

Love the longer videos btw

Good stuff in your detailed assessment and repairs 👏

The throttle interference was exactly what I found on mine just 30 minutes ago. The aftermarket carb looks the same and that rod that is interfering with the cover flashing just as yours. I cut it out to fit and no more binding.

You have more patience than I do. It would of went flying as soon as more problems occurred.

excellent video! thanks for creating.

I love your vids

Thank you! I went in search of maintenance (sparkplug, fuel filter, air filter, etc) pieces for my saw, found an inexpensive kit with a replacement carb, I thought, why not. Turns out the replacement carb interferes with the linkages. Old carb is back on again.

Great video, just the right amount of detail for somebody seriously trying to fix their Poulan Pro chainsaw - liked and subbed! I have the bigger brother Poulan Pro PP4218AV saw and finally got it to run again after a thorough cleaning of the Zama C1M-W26 carburetor and replacing the airhead body assembly (broken plastic arm), new fuel lines and fuel filter. Oiler isn’t working, I am waiting on a new one to arrive. Question on a compression tester: Several YT commenters on other channels have said the Schrader valve should be closer to the engine cylinder and not at the other end of the hose next to the gauge. Other than needing to pull the starter cord several more times to pressure up the hose, what difference would it make where the valve is located? Anyway, looks like you have a LOT of great fix-it videos. Thanks for sharing them!

I am looking forward to the 2nd video on this one.

Had an issue similar a week or so ago with a customers husqvarna. A Amazon non OEM service kit came with the air filter. Said air filter was maybe a thousandth to large on the throttle side and caused the throttle to stick at WOT.

i've had the same problem with a Poulan predator you need to cut out a piece of the plastic cover, the problem you have is the top linkage will hit the cover and cause the top throttle butterfly to open but not the bottom causing a lean condition.

Great video!

brand new aftermarket carb.. The top cover must be modified to allow clearance for the choke rod. Been there. That's before you revealed it. I had to nip off a fuzz from the choke rod to fix it. I have a lot of ,2 cycle equipment. I Uneathed a 4218AVX, last run Dec of 17. I was emptied of gas, but the carb isn't playing nice. I ordered a Zama carb kit for it. Will be here Thursday. I put that aftermarket carb in another 4218 AVX a few months ago. Not doing it again.😄😭

I usually replace rubber boot also if it’s over a year old and new home maded carb gaskets These are the best saws if you can do the repairs yourself

I noticed the issue with the carb and as I have reviewed and played your video a couple of times I have noticed that the rod that runs thru the brass bushing @ the 8:43 mark appears that it is too straight and needs to be bent outward a bit to clear the rubber seal and the cover a bit. but I did see one gentleman (James Hedrick) state that it is an after market carb and I have to agree; however I think this adjustment may work aside from replacing the carb with an original one. Very good video and rather a puzzling but challenging task. Thank you for this video!!

Well done - can't wait for 2nd episode. What I have found out with these cheap replacement carbs is that they lack a lot of torque.

I just got a 4218AVX from a buddy that gave up on it. Same problem! The carb is supposed to be a Zama W-26 which has a black plastic lever for the top air valve. He actually had the original carb in a box so I could compare and that's how I found it was the wrong carb. Gonna see if there is a gasket kit for the W-26.

I got the same issue going on also . Look forward to see what you find on it caused the issue , mine is the pp4218a 42cc but same design.

Parts is the only reason I'd even take one for free. Everyone's mileage will vary.

I definitely think the throttle linkage is getting caught on something in the cover, I would just cut some of the plastic back or try to modify the linkage so it doesn’t do that.

This is where a donor machine comes handy. Maybe the carburettor isn’t correct hence hitting, need to look at PDF of parts for that model.

Good catch. It's not always obvious when the cover is part of the problem. I have run across the "works with the cover off but not on" problem a few times along the way and it's always something different... catching\pinching ubbing\stopping\etc... I would bet a Nickle that the carb he used was slightly different than the one it started with.

I have one of those... They aren't a bad saw once you manage to get the carb tuned properly. I find they tend to not be tuned well fr the factory. I am not a huge fan of that model, they have that strange x torq style carb with the top part of the carb for only air. When they work they work well.

Great video my friend 👍🙏👍👍

I've worked on several of those small poulan/husqvarnas with the 2 inlet butterfly valve carbs. Very difficult to get them running and keep them in tune. Don't know what husky engineers were thinking.

I had the same issue with the throttle linkage,the cause is the aftermarket carburetor,you have to cut the throttle linkage a little shorter to clear the top cover.THE SMALLERENGINEGUYS video had a video on this.

You can’t judge mix gas by color. Just about every brand of 2 stroke oil has a different color or die.

I found a PP4218avx poulan down the road. All that was wrong was the return line was in the wrong spot and needed a new chain.

ive had one sitting for 7 years so this may help

What size fuel lines did you use in replacing the old ones? I have the 42cc version; it looks just like the one you fixed. I can’t complain too much as it was reconditioned when I got it nearly 12 years ago. Mine is giving me a little trouble staying running. I have pulled the carb off and was dirty; the metering diaphragm appeared soft enough to not replace. I think I need to change the fuel primer bulb, so I’ll change the filter and lines as well.

I have the 50cc having trouble vapor locking. Runs fine till gets hot. You shut it off it won't start.

Hey bro, what's up? Shubh Divali to you and your family bro. You got a nice chainsaw with a lot of surprises bro.

I just got my hands on a free cub cadet riding mower and it in super good shape

Is there a big difference of 40:1 and 50:1 mix? Some of the mixes sold state that they work for both 40 or 50:1. I love your videos you do a great job!

I literally just fixed my brother's saw it's the same one he got it free and I just had to adjust the screws for it to throttle hi and to idle also the cover on yours is probably a little warped grind that spot where it was rubbing on it

I see a ton of them every year and most likely fuel lines bad and metering diaphragm They run good and really all most folks need It’s all about name games of items

Where am I able to buy that plastic splice for the fuel tank?

Btw. No video is too long. That's actually what people want is longer videos

16:54 FWIW, I don’t care how long or short a video is if it’s well done and addresses an issue completely. I prefer one-part videos that cover everything related to one machine at the same time.

Was there ever a part 2 to this?

Does that have a heat shutter

Hi home garage I have a question so I am fixing my dad’s friends chainsaw and it’s a mcculloch 1422 av and it won’t start and I saw that it had a broken primer bulb so I took almost the entire thing apart to get to it and it doesn’t look like it has any tabs on it that you press on to pop it out and I was wondering if it was possible to just pull the bulb out of the plastic casing that you connect the fuel lines to and then just put the new bulb in please let me know what you think and if it would work or not thanks home garage

I just got one for free for the exact same reason and I can’t get it to start new carburetor and spark plug still nothing has good compression

Seams like the new carb is not just right. If it were me I would take a heat gun and move the parts of the cover that'd touching it just a little.

Is bar upside down?

Is there any update on this project? 🤔

Good diagnosis & repair, but the sort of issues you were having with that saw , makes it not worth the time to repair, plus the cost of some of the spares are outragious, just totally unjustifiable, which is why I rarely work on small equptiment any more.

That's what bothers me is tge repair shop string. Did they put it back together ,put back all the screws. You never know

easy plug the battery in, I love my dewalt 20 volt, and my arm and sholder feel much better

AllWAYS replace the rubber air boot and save your self a ton of fuel problems

What kid or brand oil are ypu

Bad intake gasket on them saws mine was bad .

Mine started after replacing the fuel lines, idled high like in the video and died as soon as I pulled the throttle. Complete junk. It's sitting by the curb for trash pickup.

Idle Screw Was In Too Far Had That Happen We’re The Choke Wouldn’t Set on an Echo and Shindawa Chainsaws 😀

[01/03/23]What’s happened to this saw since October ?

The chain righting mechanism on that machine is hopefully work,s proper

Once I discovered those first few obvious mistakes I wouldn’t trust anything else to be correct, even if at first glance it appeared okay. That especially goes for what appeared to be a new, replacement carb. So many lacking knowledge, patience or attention to detail throw a new carb at a machine, and in this case it’s consistent with the other things. I would not have assumed the replacement was the correct one and I suspect that is the reason the original cover and inside edges were abraded and cut away - the new carb is the wrong one for this saw. This may explain why the original gasket was incorrect on this carb.

Its been 10 month and there isn't a second part for this video?

Worst case scenario, modify the cover.

I like the 50cc better .

Poulans get thrown away more than anything. Fuel lines are always junked

I had the same problem with mine, I put an aftermarket carburetor on and it did the same thing. I trimed the cover , and it works fine. Mine is the Poulan 16/34 the carburetor look just like my replacement. My old carburetor had a little different throttle arrangement, it had a post that stuck out from the main throttle and it hit the lever for the top air valve. I took the piece off my old carburetor. Not sure if it helped or not. The cutting of the cover seems to have helped more.

Carb gasket wrong one

That's the classic sign of an air leak when you have a high idle like that Still way too lean I will double check those rubber boots that you replaced for air leakage.

I had to cut the linkage on the tip where it was hitting the plastic cover. Break out the Dremel, baby! The Chinese replacement carbs apparently all have this issue; Amazon shows several images of people who had to do the same. Very poor craftsmanship.

What with all the shoddy maintenance issues isn't it conceivable that the previous owner bought the wrong replacement carb? You shouldn't have to cut away seals and housing to make the machine operate properly.🤔🤕

Lol what i would give to drive 20 miles in 30 minutes. Here i drive 25 miles in 2 or 3 hours.

The original fuel looked like motor oil/fuel mix. This is never a good option.

Poulan is the most troublesome, unreliable saw on the market. Husqvarna should be ashamed of themselves for producing it. Pay a few dollars more and get an echo or a stihl.

Unless it is a high quality name brand chainsaw it is not worth fixing even when free. You are fixing something that is not worth it but for your own knowledge. In 2023 I bought off Craigslist two saws new in box never used $80 each. A Poulan 42cc 18" & a Walmart black max 50cc 20" , both never used were gifts they didn't want.

Your skills are wasted on this POS machine. A helpful video.

Saws are junk

Throw it back in the trash. Pullons suck. They run for one job and then never start again. Buy Stihl and they last forever and start every time.

It’s a Poulen, it could many problems, I hate their stuff, IMO mostly junk.

what a piece of junk never been a very good brand.

They put wrong carb on ran into problem today
