McCullogh Power Mac 310: Easy Guide for Beginners and Top Tips

Alright, so today I wanna talk about this old McCulloch Power Mac 310 chainsaw that I’ve been messing with. Found it in my grandpa’s shed, covered in dust and looking pretty sad. I figured, why not try to bring this thing back to life? First thing I did was grab the owner’s manual I found online – super helpful, by the way.

I started by taking a good look at the saw. It was clear that this thing hadn’t been used in ages. I took apart the airbox – man, that was a bit tricky. Everything was crammed in there: the carburetor, the impulse line, the fuel line, and the throttle wire. It was like a puzzle trying to get everything out without breaking anything.

After I got the airbox off, I cleaned everything up. The carburetor was gunked up, so I gave it a good soak and scrubbed it clean. Then I checked the fuel lines and the impulse line. They were pretty brittle, so I decided to just replace them. Better safe than sorry, right?

• Took apart the airbox (tricky, everything crammed in there).
• Cleaned the carburetor (soaked and scrubbed).
• Replaced fuel lines and impulse line (they were brittle).

Once everything was clean and I had the new lines in place, I started putting it all back together. This was just as tricky as taking it apart. I had to make sure everything was lined up just right, especially the throttle wire. One wrong move and the whole thing wouldn’t work.

Finally, I got it all back together. I filled up the tank with fresh fuel, primed the engine a few times, and pulled the starter cord. It sputtered a bit at first, but then it roared to life! It was a pretty awesome feeling, hearing that engine run after all these years.

Keeping It Running

Now that it’s running, I’ve been using it to clear out some brush around the property. I’ve learned a few things along the way. Like, keeping the chain tension just right is super important. Too loose and it’ll fly off, too tight and it’ll bind up. Also, keeping the chain sharp makes a huge difference in how well it cuts.

Overall, it’s been a fun project. It’s not every day you get to bring an old machine like this back to life. Plus, it’s a beast when it comes to cutting wood. I’m pretty happy with how it turned out. If you ever come across an old chainsaw, don’t be afraid to give it some love – you might be surprised at what you can do!
