Smelly Old McCULLOCH Chainsaw. Will It Start or is it trash?

[@tedcorey3054]

I got the same saw , fuel leaks into the cyl. when it sits and it hydro locks , carb. needs a rebuild like yours . The saw (I believe) is worth fixing , they don't make 'em like that anymore .

[@riderescue]

It is a pretty good little saw and it's worth fixing.

[@JakePlisskin12]

@@riderescue yeah I have 5 mini macs 2 theirs no fixing them but they look nice on the shelf. they are a 25 and a 35. so a couple less cc. and no chain breaks. but the 110 and 120 then eager beaver I have all have nice chain breaks, also all are pretty much brand new. just been sitting for a long, long, long time. my beaver runs good. but I'm getting into the other 2 soon. i got them for climbing, plus I kept finding them for 25 bucks. but even if I just getting them all in running order and put then on the shelve in the shop. I do kinda like the electric saws for climbing actually anyways. I don't know what I was thinking. honestly the battery powered saws are the only saws you should be using to climb. I have taken down at least ten trees over 40ft with my first get stupid Ryobi 18v chainsaw haha. ill be getting a still or husqy soon.

Must check the fuel line. It may be clogged in the filter in the tank or in the tiny metal net filter inside the carb.

Usually hard to get them to draw fuel from the tanks!

[@thadstuart8544]

you are dressed way to nice for that job! :)

[@rogerburns9960]

Have to do a complete teardown to get to the carb!

[@rogerburns9960]

Air gap 10-12 thousands or a slick business card will usually work!

I think you should have did a little research on the saw before you opened it up. You did not know what you were doing, nothing personal. Kind of watching the proverbial monkey with a football. Once you know what you are doing, you can take one of these apart in about ten minutes. The throttle linkkge is just an interference fit insde the case which you pop loose with a screwdriver. When disassembled, kit the carb, replace/clean the screen in the fuel inlet port, new fuel lines, and a felt/rag filter in the tank. Reassemble, set the coil gap, new o rings in the oiler and you should be good to go. There were a lot of things missed during disassembly and reassembly. When you had it apart, you should have taken the muffler off and had a look at the piston. It was probably okay as the saw seemed to have compression. Plus, it started. The rubber sleeve on the intake has to be properly inistalled for a good seal. It is unknown regarding the condition of the air filter. Don't throw old saws like this away. This one is better than the craftman electic one you showed, Where you screwed up is you did not take the saw very seriously. You have a hotrod in the background, you should know better. This little one cylinder motor deserves the same attention the motor in your hotrod does which you just took it apart and took it for granted. You did the samething a kid would do on a car and halfass takes his motor apart without really knowing what he was doing and nothing changes when he put it back together. The chainsaw was probably fine. The biggest problem with most chainsaws and there are millions of them out there. Most people who have them only use them seasonally. When they finish using them, they put them away with gas in the tank and let it sit and sit. The gas evaporates and leaves residue behind as it evaporates. Next time they want to use it, no start. The varnish residue has gummed everything up. Also, remember when kitting these little carbs, to clean them as the passages inside of them are tiny. You want to make sure that gas and air is properly flowing through the carb. Then, adjust the high/low screws accordingly.

You had it apart but didn't put the carb kit in it. Bet the fuel pump is the culprit. 🤔

[@riderescue]

Yep. I hate to buy parts for these low cost projects (like the carb kit) just find other lethal issues like a gas tank with a horrible chunk of foam stuffed in the bottom of it. If this little thing wasn't so time consuming to take apart and put back together, I'd give it another try. Thanks for watching and leaving a comment. Much appreciated.

Thank you

[@rogerburns9960]

At least 6 screws to remove to get out!

[@adventuresofmattyb1386]

Should have researched it on KZbin first people do it no time I am going to take the time and just do it because it is cool

[@tedcorey3054]

Hard as a carp .
