McCulloch Chain Saws

copy that...on my way out to take it off.

10-10 apart

Well I took the 10-10 apart. I didn't open the case but I think I might. A lot of carbon went down the hole when I took the bolts out. So far it looks like the muffler is toast it has rusted through. The clutch cover looks like it is missing a chunk? There is also a crack in the side of the coil but maybe that doesn't matter. If I open the case I suppose I could put new rings in since I'm in there, what do you all think? Not the dirtiest saw I have opened but it was trying .

...I got the clutch off of the 1-76 parts saw. It looks good, except one of the pins that holds the pawl on is a bit loose, it'd need to be tightened up somehow. Either with a hammer and some kind of special anvil (there's only about 1/4" of space behind that pin and where it attaches to...) or a nice solid tack weld

If you got a MIG or Flux core machine in the garage, you could give it a heavy tack and that might be all it needs to last forever, through ten nuclear wars and two alien invasions.

I'm a little to unsure of myself to try it... I just know these clutches are a bit difficult to find. I know that because I've more than once gone out searching on the Googles to see if one happened to be out there for ya...

Holler back.

Redstripe's Jamaican isn't it? Didn't think that looked like a Redstripe bottle on the table. Haven't had one of those in years. Sam Adams for me right now...

Hi everyone!

Just picked up a Mac 10-10 for cheap and I want to get this beast running, it will make a good "back of the truck" saw.

Problem is the saw will run without the Air filter and cover on, and it runs like a beast, but as soon as I put the air filter and cover back on it bogs down and will die when I give it gas. I tried to spray out the air filter with a compressor and adjusting the carb this way seem to be a big PITA.

Anyone got any experience in this? It seems to run great without an air filter and I'd rather not buy a new air filter for it.

Yep Jamaican, Sam Adams is great

Are all 10-10 piston rings the same? All four IPLs show the same part number. Don't see an reason I wouldn't put new ones in since I'm basically there. Can clean out the inside and check things out as well.

Carb kit. Bet a real good cleaning of the carb and a kit slapped into it will cure it, after being tuned.

Kyle -

What does a 1-76 clutch have to do with ME?

The carb doesnt look all that bad when I tore it apart and put it back together. All the seals seemed in good shape and it was spittin gas like no other. It doesnt look like a K10-SDC or a walbro carb for that matter. Dont most Walbro carbs say WALBRO right on the top of the carb?

Remember that your carb is rotated 90degrees from what you're usually seeing. The choke side is straight up (rather than back) and the engine side is straight down. Should say "Walbro" and/or "SDC" on one of the covers (should be the cover closest to the front of the saw when the carb's mounted). If it's a 'cube' shape, then it should be an SDC. If it looks like a melted frog, has no choke (but there's a primer on the right side instead), and feeds into a 90degree manifold (forward/down), then you have the Mcculloch carburetor commonly known as the "Bullfrog". Shouldn't be that carb however, as those were on the earlier X-10 saws (1-10, 2-10, etc) and not the 10-10's. Shoot a pic of the carb. "Spitting gas" usually means there's something wrong with the needle/seat.

That's an SDC. Both McCulloch and Homelite had Walbro put their names on SDC's built for them. Big customers get special treatment!

Look at Randy's first carb pic. That's the infamous "Bullfrog". Be glad you're not messing with that.

Your carb is a Walbro SDC and takes a K10-SDC kit. The adjustment needles are on the left. You can see on Randy's PM800 that it has the rubber grommet thingee with needle extensions for adjustment without taking off the AF cover. My SP-81 has a single short needle (LS only dammit), adjustable with the filter removed. Yours has both needles, but the carb box casting isn't drilled for the needle extensions. Gotta adjust it with the filter off...

Nicely done Randy. I like the 'Borg' reference for the square carb...

Thanks a ton for the quick help! Rep for you sir!

I have a 2-10 project with a bullfrog sitting right across town from him if he is looking for a challenge

 

[8433jeff]

Yes, lets keep that in state, shall we? Hate to be exporting saws, especially older yellow magnesium ones.
