Thanks for watching. This chainsaw has spark, fuel and compression but it still won't start and the reason is very common.
Your vids give me confidence to repair myself. Appreciate you sharing.
Glad to help
Thank you for this video, I have the exact same chainsaw. Your explanation on carburetor and gas lines was extremely helpful.
Glad it helped
Those have very fragile oil pumps, it's twixt the flywheel & crankcase. They're low on power & do fairly well with a 14" bar, better with a 12". Have 3 of these given to me & I won't do anything with 'em except use for parts. They're a Chinese POS!
I have no doubt you're right, Hopefully I'll get this one working and be able to use it for emergencies and that's it.
A+ Alot of hard work goes into what you have done so far, look forward to the conclusion.
thank you The Rusty Rooster.
Thanks for helping me get my Hurricane-Katrina-era McCulloch chainsaw up and running after all the lines disintegrated. I was hesitant to split the case but your video was a tremendous help! Thank you!
I really appreciate the Super Thanks! thank you Mike Luchsinger.
I'm working on one as we speak , this video is going to make it so much easier . Thank you so much 💯 appreciate it.
Glad it helped
Is that fuel line actually Tygon, the brand name Tygon USA appears in white letters on the whole length of the line I have! ?
Yes I have some real tygon line and it has the righting on it too, expensive as hell, this is a tygon aftermarket knock off I think.
that looks like a hardly used chainsaw just been sitting with old fule , my first saw looks way worse lol
thank you unknown President.
I worked on one of these for my uncle just a few weeks ago. I was able to change the fuel lines without splitting it, but it wasn’t easy. This isn’t the first McCulloch like that that I’ve worked on though, I did split the case on the previous one, so I was seeing if there was an easier way lol
nice
Great video and precisely what I needed to know for the specific model of chainsaw that I have. The message at the end gave me a lot of courage and I think I may undertake this whole procedure on my saw, which needs it, wish me luck.
Great to hear and thank you for your time!
Not bad! You got most of it right. I work on chainsaws almost every day, And yes! I do have a pile of these and mini mac saws.First off, if you don't have 90 PSI for your minimum numbers for your compression check you won't get a 2-stroke to idle when warmed up! Second thing, It's not the ethanol that destroys the fuel lines and diaphragm, But the Benzene in pump fuel does a job on rubber Ethanol will crode aluminum and also is the culprit for all the water in your fuel system! It has an extra molecule of water that makes alcohol and draws moisture to it. I would disagree that the ring was worn due to lack of oil! If there is ever a lack of oil It's because there was none mixed in with gas and always bakes the piston! Men have a tendency to put just a little more than the recommended amount because he is worried about seizing the piston! Unaware that is usually the reason the piston is all scraped up at exaust port. And a majority of the over heating problems when you got a puddle of it in the exaust pipe! 50/1 2.6 once in a gallon of premium fuel or better! I use VP small engine fuel already pre mixed. Regular gasoline is garbage these days! And the hotter it gets the worse it pre detonates and will destroy a 2-stroke engine. Here is what I see most often that stops a chainsaw from running. You have to keep the chain sharp on a chainsaw! Otherwise it makes a powder enstead of chips or if you're really good at sharpening you make shavings! It sucks it into the holes in the flywheel side and mixed with the thick bar oil sold to you, It makes a goohy mess and slings it across the face of the coil and that's the end of your sparky,Sparky!😉
thanks Tony Mayhew for all the information.
I made reply on older vid for parts on this Mac. Where are you getting carb or diaphragms now. Two years ago I found parts having trouble now. Thanks for any direction.
I would say that you need to get in contact with Leon from Leons chainsaw parts and repair! Located in Southern Oregon State. He is a homelite chainsaw guru! And he has a business repairing and he also sells parts for several different brands,And one of those brands is McCulloch! Great guy and I personally think he is the best videos on TH-cam for the proper procedures for repairing chainsaws!😉
Mine has no spark for some reason, worked fine last year no one touched it. Has the cheap plug from the kit that came with the fuel lines. Could it have gone bad that fast?
Thank you for sharing this. I am just a wanna be fixer guy....and I loved this chainsaw....it has been sitting for too many years and your video demonstrated how simple everything was....AND paying attention to details helped too. Looking for many more helpful hints from your site
thank you Doug Arvidson
I change fuel lines all the time. Running the system dry is what I do also and I have never had a problem .
thank you Brian King
It also helps to avoid using ethanol in these small 2 stroke engines...
very true
Same chainsaw as mine, i looked for a video as my fuel lines had cracked - Thanks this video saved me alot of messing about.
Glad it helped
Great video, showed exactly what needed to be done to change the fuel lines. Thanks for posting this!
no problem
Hi, first many many Thanks. I enjoy your videos, and this one gave me confidence. Looking forward for more videos, again Thanks!
No problem and thank you for the comment
Good job brother the only problem is you need small hands to do this repair.. I would of lost my rag with it without the first 10 mins lol
absolutely, you're quite the man Mick. You make all your equipment look like kids toys, especially that Hyundai mower from the other day.
We have Gas Fuel Line Kit that may fit your equipment. We're happy to offer you the product completely free of charge in exchange for a video review. Do you need?
no
Thank you for making this, I'm not looking forward to what you did that I'm about to do but it's not worth selling, I know it runs but yeah primer bulb is shot and I'm assuming it needs fuel lines as well. Yay here we go
good luck and it's not as difficult as it looks
Ok I took out the plug, left it connected and check for spark, got nothing...that explains why it won't start. It was a cheap plug that came in a kit. Tried an old AC Delco plug for a car and no spark on that either but it has a large gap...so no idea if the plug is bad or not. It was a cheap plug that came in the kit with the fuel lines.
looks like your ignition coil is bad. good luck fining one of those.
Oops, 6:30 says to put both lines from the bulb to the carb.
I have a mac 3200 and the piston goes up and down put seems to hit something and stop at the top I enspected the piston not scored so I attempted to take off the bolt on starter side but It made a full up down as it broke threw what ever was stopping it the bolt didn't come off I that kept spinning it and it became easier and easier to turn after time , I got it started it ran for a few min but now all lines fuel ect are cracked any idea why it may have been so hard to make full rotation or what it may have been hitting, thanks
I would only be guessing with the information that's been given. I'm going to go with a carbon deposits or some rust.
Dontou recall if the 3/16th is the inside diameter or the outside?
Just aquired this chainsaw and these videos are incredible!
Inside Diameter
If it ain’t broke, I don’t own it! I would fix it!
1:30 can't you just take out the plug, leave it connected and check for spark with the spark plug outside the unit? Most people don't have the tester
yes you can.
Have a Homelite string line trimmer that my kid brought home along with two other mowers found at the curb.
The mowers seem to work okay, although one needs a new throttle cable..
The string trimmer had fuel in... And I smelled it.
Straight gassed.. showed my kid what happens to the piston when straight gassed, and he saw the scoring.
Well, now I seem to have some extra parts... Even a dead one has some use.
sorry to hear that happened
That's okay, he thought it was cool and now knows what to look for in them. The two mowers, tho . They are gonna be fun! He's looking forward to fixing up one. Nice bonding time ,😊
I totally agree
How old is this chain saw? and Happy Thanksgiving!!!
happy thanksgiving too, it's over 20 years old
Love these old mac saws I have a super old one I need to repair that be fun #repairgang
good luck with it Simply Andrew's Repairs
Здравствуйте. Я из России. Мне очень нравится такое необычное расположение двигателя. У меня две такие пилы под восстановление,одна на продажу,вторая себе в коллекцию. Мне нравится американская техника. Несмотря на небольшой объём двигателя у него хорошая мощность.
Большое спасибо за комментарий. Да, мне тоже нравится этот двигатель, даже несмотря на его конструкцию.
What Carburetor Model and Number did you use for the saw
not sure since I didn't need to find out.
Great video, looking forward to part two. Keep up the good work 👍🏻
thank you Catcha Cow
Great instructions but I have one correction. The short port on the primer goes to the tank and the longer one goes to the left side of the carb. I did it the way you mention and the primer does not fill up with gas. I swapped the lines and now it does. If you look closely above the short port it says "IN".
no, every purge bulb I've seen, with two different lengths of ports, the long one goes to the tank. if you take the purge out, put two lines on to it, and then put the lines in a jar with gasoline this will confirm this.
@@INSIDEHOUSEGARAGE I did this test before I posted. First with the hose from the long port in a jar with gas and the primer did not fill. I then switched and put the hose from the short port in the jar and it primed. I did this with both the original primer from the saw that later cracked and with the new one I got from Amazon. If you put both lines in the jar with gas of course that will work because its drawing the gas from one of the ports :)
I bet your pretty happy to have one of these working saws
absolutely, It's nice having a small saw around.
THAT WAS SPOT ON AND VERY DETAILED, THANKS FOR POSTING
You're very welcome
i have just been given one of thies 🤣how random thanks for vid
No problem 👍
I have McCulloch 3816 saw I purchased new 20 some years ago. My fuel lines are all cracked and disintegrated. The question is no one knows is the top or bottom hole in the fuel tank for the fuel filter? My lines were all broken off so I could not tell. I called the company now who owns McCulloch and they had no idea. I noticed in your video you put the fuel filter in the top hole. Do you know for sure it was originally like this? I want to keep it like it was from the factory. Thanks. Dan
thanks Dan, If I put the fuel line at the top hole, then that's where it goes .
It all depends, Donyboy73 (Don Desjardins) says mower shops would charge 1 hours labour in Canada to repair it which costs $100-$120 CAD so I would do it myself since I have the abilities & patience to do it.
He was explaining how a chainsaw which had a tree fall on it wasn't worth repairing because the plastic parts broke on it despite the engine,oil & fuel tanks,etc were still alright om it,the cost of parts & labour was only $100 CAD less than buying a brand new chainsaw !
that's is quite amazing. thank you Russell Booth
Just bought a goped for $75. Had to do this and epoxy the intake together. Today I'll be replacing the clutch and it should run like new!
nice work
Those are junk! It may start but that'll likely be the best news you'll get. The oil pump is usually the 1st thing that breaks. It's twixt the flywheel & the crankcase. How many of these do you want?
I don't want anymore of these. Thanks.
I bought the green 3/32 line and that was tight as can be to pull through will I have any leaking issues/ lack of fuel? It does idle great but having problems with higher revs. I didn’t tear into the carb yet but I’m guessing I need a carb kit.
no it's not going to restrict it, and it looks like you'll need to adjust the H screw, and if that doesn't work, then look into the carb.
Just got a free "brand new" still in the box, never used Mac 3216. This video is so helpful because, of course, the bulb and fuel lines had dried and cracked.
nice, good luck on Changing them.
I can't believe I found this. I have this exact model chain saw and it would not run. After investigation I found that the fuel lines were bad, just like in the video. It has every detail I need to fix mine. Thanks for doing this. Now I just hope I can find the parts.
thanks, and good luck to you on it.
Thanks so much! This is exactly what I needed to fix my McCulloch Eager Beaver 2014. (I think it's the same saw.
Glad it helped
Very helpful video, I found one chainsaw in the rubbish. Barely used but won't start. Fit a spark plug that was missing and make it run with fuel in the carb, but couldn't figure out the fuel lines. Now with this video will be very easy to put it back together
Glad it helped
I just want to thank you for this video that has been so helpful to me. I just got one mcculock and am going to replace the gas lines. It will be now much easier to do. Thanks again.
You are welcome!
A friend of mine gave me a Mcculluck 14”bc he couldn’t figure out why it leaked oil, I took it apart and found that the threads on oil tank had split, where can I find another oil tank.
3200 Mc
TIA
unfortunately that's happened to me too, and you cannot find them, they no longer make any parts for them.
@@INSIDEHOUSEGARAGE I was afraid you were going to tell me that, ok well I’ll see what I can do,
Thanks for you’re reply.👍🏽😉
no problem
I was able to locate a used oil tank on eBay..👍🏽
Fits perfectly fine .
Dang. Good job. You did a good job cleaning. Same with your last poulan blower video. That piston and ring was shiny
thank you Small Engines 101
What size did you use for the fuel and oiler lines?
I believe it's 3/16" OD
I run my echo cs 300 evl without a muffler
wow, isn't a bit loud without a muffler?
@@INSIDEHOUSEGARAGE you get used to it and cuts way faster
mac tech here. You will find these clam shell models for free or cheap alot. You can rig after market parts to work but we refuse them. The labor and part rate is far more than the saw is worth so people throw them away.
yes agreed and thank you for your time.
yeah, i'd definitely have fixed an old Mac chainsaw for sure. but, MY GOODNESS that looks like it was SO tedious to do!! lol I have huge hands, and fat fingers, and i'd have definitely had trouble fishing the fuel line up to the tank. Great video man, i love your content, thank you!
lol... Yes smaller hands help out in this very rare occasion.
I don’t use mcculloch saws however I do like them. I use a stihl ms250 and that’s not too bad to redo the lines. I guess if I had to do the lines I would but I prefer not to
I know how you feel
Did this exact repair on a MacCat saw I got from a yard sale that is almost identical. I wish this video had been available then as it would have made the job much easier. I had the additional problem of the cork gasket for the oiler cap rotting and spilling debris into the bar oil which was the pulled into the oiler by a broken line that separated from the filter. Took quite a bit more disassembly to clean out all the oil journals. Wonderful saw tho, I’ve used it to clean up after 2 hurricanes and a tornado and it cuts like a beast despite being 20+ yrs old.
thank you Paul L. yes it sounds like you did a great job getting your saw working again.
nice film, greetings from germany
Thank you very much! And greetings!
Great video. It will help me to repair my Silver Eagle 2000 series. Thank you!
Glad to hear it! Thank you FP
Great video. I am definitely not doing this myself.
I can understand why
So I did end up doing this myself, it wasn't as bad as I thought. However, I did not split the case to get the fuel lines into the tank. Instead I fed line up a stiff thin metal rod (in my case it was a thin braising rod, but a coat hanger would do) and it fed the line straight into the tank. On the other end of the rod I made a small hook to pull the line up from the fuel tank to put the gas filter on. All the rest was pretty straightforward. Thanks for the great video.
I agree with you in purging all fuel from the fuel lines and carburetor will help keep the components in good shape, i personally drain all fuel from all my equipment if i know they will be stored for more than a couple of days and it really helps to preserve all the soft parts, i also believe prolonged fuel exposure causes a lot of damage
And as for the comments that purging the fuel will dry out the diphragms i really disagree, if that was true i guess all the diphragms would be already bad from the packaging
Thank you Imanol Berecibar Barroso.
what an excellent detailed description in simple laymans terminology well done from sunny australia!!
Many thanks Peter Stefaniw
great video - going to help me get my free chainsaw running (hopefully!)
Good luck!
Great video, thanks
Glad you liked it!
Good on point video. Thanks
sure thing!
What size line did you use?
3/16"
I would have a go now myself having seen how you did it, but boy what a lot of work to replace the fuel lines .
I know right
I apologize Wrong video
oh.
Excellent video.
Thank you very much!
Yay! I've been waiting for this.
I can't wait to see this thing run.
Hope you enjoyed it!
yes it's coming up soon.
I have a saw just like the one on this video, I have been all over the web trying to find one who carries these parts. I need a set of the started paws on the pull rope. Would like to find more info on this saw for future reference., thank you for your help.
good luck finding the parts, I do believe finding a used one for parts is your best bet
@@INSIDEHOUSEGARAGE Thank you, Ill keep looking.
I would do the work myself. That’s how you learn to do things yourself.
very well said
I have a chainsaw that needs the fuel lines replaced. This is a good refresher since I haven't worked on one in a few years. Looking forward to the video on the carburetor.
thank you Vernon Bruce.
house garage should be short videos and inside house garage should be the longer repairs
that's an interesting idea.
Do you have any confidence with fuel stabilizers?
yes, but they are not "Cure alls" they have their limitations.
Trying to fix my chainsaw that I have not used in years. Thanks for the video!
Glad to help
Thanks for this video it helps me a lot to fix my chainsaw :)
Glad to help
Wow that saw was a mess!
I know right!
It didn’t even run and it still ran better than mine lol
lol,, thanks The lawn channel, the next part will show it running and cutting.
Great job! Yes I have replaced fuel lines on my old home lite which is a pain to do too. 😂
yes the older smaller homelites are pain as well
I would try it
thank you Lorraine Rhoades.
That's the right way got one same as that one great chain saw and video thanks
You bet, thank you Danny Henderson for your time.
Fantastic! Just what I needed to get the fuel lines installed!
Excellent!
Thanks I will try tomorrow. Thanks for sharing
let me know.
I would still make sure that oil cap does not leak.
yes I'll have to watch for it.
same
thank you Karyn Clements
Hey was there a bar spacer (gas tank side of the bar) with your saw? And how long was your bar? Thx
I didn't take the bar off so I didn't see one, are you needing one?
@@INSIDEHOUSEGARAGE no I believe the saw doesn't come with one. My issue is a loose bar, even after snug bar nuts and tensioned chain. May need new bar and chain.
I purchased the saw used, I just realized the chain that came with it may have 2 extra drive links making it a tiny bit too long!
Chainsaws are a pain
yes they are
yes they are
Another great repair job done. Cheers 🦘🇦🇺
Thank you Tyrone Clarke
Old mccoulghs are great
they are definitely unique
Excellent. Thank you.
You are welcome!
Great video! Great find!!!!!
Thanks!
I think I see why they discontinued this saw...
it seems pretty apparent
@@INSIDEHOUSEGARAGE I've worked on three of them in the past 3 or 4 years and they can be a pain...
I completely understand
@@INSIDEHOUSEGARAGE I have one in my garage right now, has good compression, spark, but I can't get it to hit even when I prime it...
gotcha, have done a compression test on it? I'd like to get a reading on the engine if you don't mind.
Great job
thanks!
I am retired and started up a small engine service and found that one of my best tools is my cell phone. I take pictures of fuel lines, carb. linkage, etc. It saves alot of fustration especially if your old like myself and your memory isn't that great. P.S. I really enjoy watching your videos they are a great help and you have some good tips/advice.
thank you, that means a lot to me.
Fun small saw. We have two taiwanese copies of this saw both 38cc. Both have oiler issues. One excessive oiling and now no oil anymore and the other one no oil. So I need to take them apart both to check the oil pump and line. Carburetor type is Walbro WT439. One saw has probably issue with the carburetor (checkvalve or metering diaphragm issue -- flooding ). If idle speed somewhat low it falls on its face when releasing throttle from full speed
Yes I believe your assessment is correct.
@@INSIDEHOUSEGARAGE need to check the fuel inlet of the carb by pressuring it to check for any leaks such as the needle
yes that is something I need to do.
👍👍отличная пила👍👍
