MCCULLOCH The official McCulloch thread

[heimannm]

Maybe when they get the final bill they will rethink leaving off such things and expecting miracles...

It still doesn't look like much, but is certainly runs and oils well.

A friend of mine stopped by this afternoon to show me his latest haul.

I like all the ones without chainbrakes!! Was that from an estate sale?

 

[heimannm]

In a sense, yes. Younger fellow (around 50) passed away quite unexpectedly. He was a collector of saws with an emphasis on McCulloch but there are others as well. We are supposed to go have a look at the remaining saws and parts this week some time.

That is a bummer, looks like he enjoyed the saws while he had them!!

Well fellas,there's something amuck with my SP60.Either someone changed out the original carb,or I have a weird SP60.The IPLs I have show there should be a boot/grommet for the needles,plus there's supposed to be an idle screw,my saw has neither.There is no opening on the tank handle for the boot/grommet or the idle screw..I'll be posting pics later to confirm this.

Is this the boot you are missing?


From what it looks like in the IPL, there are three potential carbs for your saw and only one has an idle needle.




I am guessing you have either #1 or 2 and are wanting #3 with the idle adjuster (#17)

 

[hacskaroly]

Here is a pic of another SP60 that I am guessing is set up like yours without the adjuster holes:



Some of the earlier Husqvarna's required you to take off the air filter cover to adjust the idler screw, I wonder if some of the earlier McCullochs were the same way before they got smart and put adjuster holes in them.

 

[heimannm]

With McCulloch you need to try and match the model and serial number of the saw with the IPL to make sure you are looking at the right parts.

I have (had) an early SP60 with out the external adjust access, note that this one have the provision for the external idle adjust in the AF cover, the one pictured in hasckaroly's post above does not.



I also have some later release versions with external adjustment and the cold weather kit.



There were other variations as well, some with a chain brake and no hand guard, some did not even have the provision for the hand guard like the first one pictured above.

On some models, like the 7-10 there were vast changes from the first to the last iteration.

The earliest models had the lever type compression release, throttle lock and stop switch were built into the compression release, and the early type short clutch cover that would accommodate the full wrap handle bar.



The final version had a pop up compression release and a trigger release in the rear handle. They were also equipped with a chain brake on the later style short clutch covers.



There was at least one intermediate version as well with a pop up compression release, the larger profile short clutch cover, and no trigger release.

Thanks for the input guys.Shortly after I made my post I took a look at the settings on the carb & they were waaaay off.Apparently the idle is set with the lo needle.I set the needles to 1 1/2 turns out from seating & it fired up but ran a tad fast,so I turned out the lo about another 1/4 turn & it runs perfectly.Yes,there are no adjustment holes on the tank handle or the AF cover.If anyone is familiar with the Stihl saws (MS250,MS290,MS310,there is no idle screw on them either).The carb settings on my SP60 must be done with the AF cover off,just like the older 10-10A.

Apparently the idle is set with the lo needle.I set the needles to 1 1/2 turns out from seating & it fired up but ran a tad fast,so I turned out the lo about another 1/4 turn & it runs perfectly.

Glad to hear that you were able to get it dialed in!

I went to put the ignition module on the J'red 535 yesterday & it's the wrong one.I had to buy another used one that should be the correrct fit.Today I unloaderd the trailer that was heaped full of bark & chips from splitting into the fire pit,there's a fire waiting to happen there.I think it's stacked up to about 10-12 ft.tall & quite round! Gotta wait till the 15th cuz there's a ban on burning even though it's been raining here for close to a week & there's local flooding south of where I live.Probably can't go out cutting for another week,may have to wait till the farmer tills under the triticale toward the end of the month.I still have lots of stuff to do.

Ed - I have some notes that tell me the early SP60 saws would have been equipped with a Walbro SDC50 carburetor that has the internal idle adjustment (built into the carburetor body) and a fixed H jet. The only photo I have that is close is this SDC40 with adjustable H and L. The idle speed screw is on the left just above the throttle arm.



Without matching the model number and serial number of the saw to the actual IPL it is had to say what might have happed with a McCulloch saw over the past 50 or 60 years.

Mark,here's what the SP60 has for a carb.It might be difficult to determine what it is.

 

[heimannm]

The screw located near the throttle arm is the idle speed control, it goes through the body of the carburetor and actually contacts the throttle butterfly. The other screw is the L jet/mixture adjustment. The H jet is fixed.

That one polished up nice!!
