I just followed your video. Changed out the carb. Was a 100% sure about the placement of the gaskets and the spacers and mine were pretty rotten. Long story short. It starts up revs twice and turns off. Any thoughts?

Thanks for the video.

Appreciation for your attention to detail.

idles like an omc outboard

Excellent idea for bench testing it!

Good to see some new videos.

Your audio is very bad can hardly hear you.

Dumb Question, how did you get the screws out to remove the recoil starter? I cannot get to mine without a big disassemble it looks like?

Great video for fixing oil pump hose . Thank you

Thanks for the vid, I've got a shindawa version thats not oiling (but hasn't been cook) ill have to investigate.

Hey so on the mini macs are all the parts somewhat interchangable. Becuase i have a 25, 30, 35, 110, 120, and a angry beaver 2.0. My goal is to get the 25(its my dads first chainsaw and my first mini), 120, and the angry beaver working realible. If i cant get them all running.

I bought one of those, is this a 2 stroke or 4? Thank you for your video.

Can you tell me what were you checking with the gauge attached to the fuel inlet fitting? Was it vacuum or pressure of 10 on the gauge ? Thanks

What are the resistance specs on the ignition coil.

I inherited one of these, not sure the exact model as the sticker is missing, but I have to give a full service, I've always hear my grandpa and my dad saying it has an oiler problem, it's been sitting for years. The plastic handle is missing but I guess it's not the exact same model as mine doesn't have the peg on the other side where it attaches too.

very nicely none-lots of info

What was the rebuild kit?

Thanks for sharing this! There's very little information about this model on the internet, and much of what's out there is incorrect or questionable. I can't find an original manual or parts list, so videos like this are an asset. I recently got one of these saws from eBay and got it running with a little work. All of the head bolts and the bolts for the transfer port cover were backed off so it was sucking air like crazy! I also cut a new gasket for the port cover which was easy enough. I installed lock washers to keep things in place. I'll have to try your spring-in-the-hose trick when I pull the carb off for a rebuild.

Really appreciate the whole process you showed with this one! I recently picked up a 160s with the case and bar cover for $20, I really love tinkering with all sorts of mechanical things so I figured this would be a fun challenge. Your videos have been such a help for all the things that I've had questions about along the way, and all the little tips and tricks that only come with years of experience. Currently, I've got everything cleaned, the carb rebuilt and I'm getting a spark - started seeing some combustion for the first time yesterday when I cranked it up but I haven't gotten it to run yet. Two things that have happened along the way that I wonder if you've encountered or have a fix for: First, the threaded plastic piece has broken in half in the back of the handle - I assume someone over-tightened them at some point and cracked them. Is there any way to fix that or should I just look to buy a new handle? Second, when I first took everything apart and got it fully degreased/cleaned, I pulled the fuel pickup from the tank and haven’t found a new one. Is that something that needs to be replaced or will it run without it? I also was curious if there’s any type of fuel filter on these models or if that acts as a sort of filter as well

My throttle screw on my 120 keeps vibrating out the second I hit the throttle. I put some blue loctite on the screw idk how long that going to last.

Yeah i cut my fuel like long as always then realize it kinked. Kept having to widdling it down. I always get worried about the tank plug outlet not seating for the fact that it so hard to get it off. So i plug it in the tank first then slide the engine in. Then just pull the tank out a little bit. Just enough to get a fish hook shapped pick to connect the throttle.

Yeah id say put that Beauty on the shelve and find one that been through the ringer. Im sure you can fix it up

Bonjour je suis français et possède les deux de chaque grand père et fonctionne encore une 200 et une 250 ensuite encore une 250 et une 300 carter noir chaîne pas 404 mais ôu trouver les menbranes ? Chez nous elles étaient importées de Belgique Aastrat Mechelem

You have to heat the wire first to give the soldier something to stick to and you could also try using a little flux that will help the solder flow good repair techniques thank you

So you can switch all the types of carburetors on all those mini mac. Because i have a mini mac 25 with a mdc-1 and a mini mac 35 with a mdc 6 carb. So it would run fine if i swapped the carbs. What about switching the coils and condensors? Becuase the 35 coil and condensore has a open loop. And i wanted to put the 25s on the 35. If that makes any sense. Idk i cant for the life of me get these things running. Im getting a mini mac 120 in a couple days for $25. Really hoping i can get that one running.

I have one of these and it's got this same barrel on the idle adjust screw. I had it running great yesterday, but then decided to try to make it run better. Big mistake. Now I'm having trouble getting it to run well again! How many turns out would be a good starting point? (I wasn't smart enough to count before I fouled everything up. Argh!)

Hard to see and follow what is taking place

I also have WT346 carb. Do you mind sharing the carb number? Thank you

I think its called a v ring.

To jk McClead where can I get a carb for Mac 3200 looked everywhere Zama carb needed ! Thanks

My dad used to have one of those in the very eary 80s. Sorry, but is it just me or do those little McCullochs sound very special and unique? I mean, Chainsaw is chainsaw, but when you started that one i had goosebumps immeediately....much deeper and more powerful than they might acutally are. Thank you for preserving that little gem :)

I came looking for baseline settings andbtuning help. But it seems like basically you're telling me that the oem carb is unworkable, right?

I have a saw that we bought on our farm. How would I go about identification, getting parts stuff like that? Would I be better off to buy a parts saw? It's locked up at the moment so I don't know what this is gonna turn into. This thing has been hanging in a barn for probably 40 or 50 years.

So how do I find a new carb for that saw I need one

It’s a major problem to keep the engine clean on these saws and half a day doing it Just don’t like the style of them for that reason only but are fine saw😊

Please turn up the volume for us older folks. Ok Thanks 🙏

Looks new and just needs carb kit and lines. Be new again 😊

Where can you find a compatible fuel primer

Can i get parts for this saw

What a bout parts for this saw

One of my mac 610 does the same thing.

I been collecting saws for a few years. And these mini’s Id toss in a pile (like 12 of them) cause they looked painfully aggravating to work on.. Your videos have been excellent tutorials once you do a few of them along with your video how to repair its not bad at all. Thanks again

Nice video showing how these work. Thank you. I have one identical to the one you have here. I'm having trouble figuring out what chain i get for it. Do you know, and if so could you tell me? Really appreciate it in advance.

Thanks for the vid. I watched your #2 vid first and then this one. Both great vids!

I have one of these, I need to get it running. Thanks for the vid!

How do you change piston on a McCulloch 120

I rebuilt the carb, replaced the lines, and reassembled mine a couple years ago and let it sit because it wouldn't keep running. Today, picked it up and found the fuel line kinked, as you warned against. Anyway, I have an unrelated question regarding the oil line, how the heck does it work? The line (p/n 84653) is 3-pronged unit, one from the tank, one to the pump, and one to the bar. But one of those prongs ain't got a hole in it!! That line just supplies oil from the tank to the pump? Oil from the pump to the bar by an internal passage? UPDATE: Went back to the machine and realized this isn't an automatic oiling machine, there is only a manual pump. Starts up and runs now, a nice little unit.

where in the @#$%$%&^&**(((is the spark plug location on this saw?????>

Thanks for the video. I have one. Its leaking fuel out of the hole you put the primer rod in to tune. Im at a loss. Do you know what size orings go on the fuel adjustment rod?

I have a question if my mccullough 120 doesn't have a chain brake it has the cover for the clutch but not the chain brake can i just get a whole new cover and put it on an it'll work or no
