That is a nice saw, I was curious, I've sold 4 on eBay since the spring

It's very possible the bar oil is too cold and won't flow. Try some 5W motor to check for flow, I wouldn't cut with that thin oil though. It wouldn't lube the bar properly.

My remington pl4 says to use a mixture of diesel fuel and oil, wierd huh?

Yeah, I think some of my owners manuals say something along those lines

The old McCulloch documents always mention thinning bar oil with up to 50% kerosene for cutting in cold conditions...

I think it is much more likely that one or the other check valves are hung up, in the very worst case you should be able to get something out of it pressing on the manual oiler button even if the oil was thick.

Bad news is you will have to remove the fuel tank to check the manual oiler function as the manual pump and inlet check valve are there, the automatic pump with the outlet check valve are under the oil tank cover.

Thanks Mark,

I had the fuel tank off when I rebuilt it, there was a little orange colored disk and a gasket under the manual oil pump, i replaced the gasket with a NOS one.. I even popped the cover off the manual oiler on and cleaned it out. BUT, when I had the bar off last time I pumped the manual oiler a bunch and all it ever did was squirt a few splashes of oil and most air, I thought it was working but wasn't pulling oil for some reason.

That disk is the check valve on the inlet side of the pump.

The outlet check valve is a small ball and spring under the cover of the automatic oiler.

Either one could be at fault with the symptoms you describe. You can try a little WD-40 or something like that into the oiler outlet, maybe you will get lucky and dislodge a particle from the outlet check valve.

Are you sure the oil tank is full? Did you get the pick up line properly seated under the check valve?

The tank is for sure full. I didn't do anything with the pick up line (unless I did it unintentionally), do you mean where the pickup line attaches inside the oil tank?

 

[heimannm]

Yes, where the oil pick up line seats in the tank. If you are not careful you can get it cocked or pinched a little bit then the disk won't set properly and seal as it should.

Oh yeah, I remember now. The hose end is large and the orange disk just sort of sits right on top of it. Crap, I hope it's not that because it's a bugger to get to.

10 Series Manual Only and Manual and Automatic oiler diagrams from the IPL's.

From the IPL's that I have, it looks like only the 1-10 and very early 10-10 saws were manual only, all of the others had both manual and automatic oiler functions.

Mine definately "HAS" both but neither work now. If the WD-40 suggestion doesn't fix it I will have to put this saw on the "fix it in the winter" pile.

Any ideals on this one? D70?

Picked it up at auction. Guessing it might be a d70? any help would be great.

Should be some numbers stamped into the casting on the bottom of the saw.

Whereabouts in IN are you?

 

[ELECT6845]

One more mac 15?

mac 15? Came from same auction

 

[Eccentric]

My guess is D-36 (for the first saw with the center-pull starter and the manual oiler ahead of the handlebar). The second saw is a Mac 15 for sure. I can't tell because the starter handle is blocking our view of the carb..............but does that saw have a Tillotson HC (like an HL, but without a pump section), or is it a Walbro SDC 'cube' carb? I've only seen HC equipped 15's in person, but have seen the SDC setup for a 15 in the McCulloch Carburetors publication. It'd be neat to see an SDC equipped 15. I'm guessing yours might be one, based on the little I can see.

Cool .... did you get these from Dinky's or from Croy Creek?

 

[ELECT6845]

Came from an auction in Morgantown In. I got a Homelite 360 and 450. The 2 macs as seen. Poulan 361 and a couple old David Bradleys.

Sounds like you had a great CAD day...

 

[heimannm]

D-30 or D-36, both had the center pull starter and either one could have come new or been refit with the manual oiler as shown.

Original equipment on those saws would have been the "LubriMac" system the collected crank case residue and redirected it to oil the chain, required running a 10:1 mix and was not too successful.
