McCulloch 10-10 Questions

[Poodle_Bruce]

Howdy folks,

I picked up a McCulloch Pro 10-10 Automatic on the cheap, and I have been using it to help my buddy clean up his property. This old saw still gets work done! I did some very basic maintenance when I saw how available parts are: New air filter, fuel line, spark plug, cheapo 20" bar and chain, & chain guides. I used to help cut firewood and worked landscaping where I ran a variety of saws. This is the first chainsaw I have owned, and I do not have any experience with older saws.

I had a few questions:

- How long should my bar oil last? I am going through 2 or 3 oil fills per gas tank.
- Any recommendations on chain tension? I have been struggling to find where this saw is happy. (Problem is probably my cheapo bar)
- This saw is still running on points and condenser. It starts pretty good, but should I throw a chip in there?
- I have not opened the carb, but I think it might be due for some new internals. Right now it cuts best in the middle/lower end of the power range. Is that typical? Should I expect more chain speed? I am having a hard time adjusting the carb to a happy cutting speed.
- Any tricks for making the handle wider? Cheap bar wrap? Maybe like a 1" fuel hose? My hand cramps, but I usually need a break by then anyway.

I know this is not going to be as "user friendly" as my buddy's new Stihl, but I certainly can't hear him when it's running. I would love to hear your 10-10 stories.

Thanks for the help!

Some guys put the plumbing isolation that people put on hot water pipes in house. To adjust the oiler I think u have to remove the front cover and there is a screw to adjust.
you carb may need rebuilding or you have an air leak. Should run best at full throttle under load.

Plumbing insulation? Is there a tougher version than the soft foam I am thinking of that you can rip by hand?

Oiler adjustment seems like a no-brainer! I'll take a look.

I'll look up a carb kit.

There are a couple dedicated threads in the Chainsaw Stickies section, one for McCulloch Chainsaws and another as the Unofficial Mac 10-10 thread. I think you will find more answers if you try in those threads.

Thank you!

The McCulloch thread is only at the top of the Sticky section. There is so much information on this forum, a guy gets lost.

You want baseball bat grip tape.

Oooh! Great idea. I guess bicycle handlebar wrap would work too.

It should cut best at wide open throttle.

A saw this age? Not a surprise. Order an OEM (walbro or zama depending on what’s there) referencing your carb model number. Deep clean the carb without compressed air. Check meter lever height (walbro w or zama z tool). Check carb and case for pressure.
